Alecia Beth Moore (born September 8, 1979), better known by her stage name Pink (often stylized as P!nk), is an American singer and songwriter who rose to fame in 2000 as an R&B singer, but then switched to rock and pop rock.

Pink's debut album, Can't Take Me Home, was produced by Babyface, Terence "Tramp-Baby" Abney, She'ksphere, Dallas Austin, The Specialists, and Steve Rhythm, and released in April 2000. It was certified double platinum in the U.S, sold 5 million copies worldwide and produced two U.S. top ten singles: "There You Go" and "Most Girls" (also a number one in Australia).

The album's third single, "You Make Me Sick," was a U.S. top 40 hit and UK top ten hit in early 2001 and was featured in the film Save the Last Dance. The song "Split Personality" was featured in the film The Princess Diaries. She was the opening act for 'N Sync on their American tour in the summer of 2000.

In 2001, she recorded a cover of Labelle's 1975 single "Lady Marmalade" with Christina Aguilera, rapper Lil' Kim, and Mýa for the soundtrack of the film Moulin Rouge!. Produced by hip-hop producers Rockwilder and Missy Elliott, the song topped the charts in countries including New Zealand, the UK, Australia and the U.S., where it became the most successful airplay-only single in history.

The success of the single was helped by its music video, which was popular on music channels and won the MTV Video Music Award for Video of the Year. The song won a Grammy Award – Pink's first – for Best Pop Collaboration with Vocals, and provided a boost for the four performers' careers.

The album, named Missundaztood because of Pink's belief that people had a wrong image of her, was released in November 2001.

Its lead single, "Get the Party Started" (written and produced by Perry), went top five in the U.S. and many other countries, and number one in Australia. At the 2002 MTV Video Music Awards, the music video won in the categories of Best Female Video and Best Dance Video. The album's other singles—"Don't Let Me Get Me", the Dallas Austin-produced "Just like a Pill", and "Family Portrait"—were also radio and chart successes, with "Just like a Pill" becoming Pink's first solo UK number-one hit. The singles were substantial hits on Adult Top 40 radio.

Missundaztood was certified gold or platinum status in more than 20 countries, with worldwide sales of 13 million. It was the second best-selling album in the UK during 2002. Missundaztood and "Get the Party Started" earned nominations at the 2003 Grammy Awards for Best Pop Vocal Album and Best Female Pop Vocal Performance, respectively. In 2002, Pink started a headlining American, European and Australian tour, the Party Tour; later, she became a supporting act for Lenny Kravitz's American tour.

"Feel Good Time" was included on non-U.S. editions of Pink's third album Try This, which was released on November 11, 2003. Eight of the thirteen tracks were co-written with Tim Armstrong of the band Rancid; Linda Perry was featured on the album as a writer and musician. Though Try This reached the top ten on album charts in the U.S., Canada, the UK and Australia, sales were considerably lower than those of Missundaztood; it went platinum in the U.S. and sold over 3 million copies worldwide, a commercial flop compared to its predecessor.

The singles "Trouble" and "God Is a DJ" did not reach the U.S. top 40 but went top ten in other countries, and "Last to Know" was released as a single outside North America. "Trouble" earned Pink her second Grammy Award (for Best Female Rock Vocal Performance) at the 2004 Grammy Awards, and "Feel Good Time" was nominated in the category of Best Pop Collaboration with Vocals. She toured extensively on the Try This Tour through Europe and Australia, where the album was better received.

Pink took a break to write the songs for her fourth album, I'm Not Dead, which she said she titled as such because "It's about being alive and feisty and not sitting down and shutting up even though people would like you to."  The album's release in April 2006 through LaFace Records was a substantial success throughout the world, particularly in Australia. The album reached the top ten in the U.S., the top five in the UK, number one in Germany, and sat at number one in Australia for two non-consecutive weeks, though it was Pink's lowest seller in the U.S. until the success of the single "U + Ur Hand" in early 2007. The album ranked 96th in the USA during 2007.

Lead single "Stupid Girls" was Pink's biggest U.S. hit since 2002 and earned a Grammy Award nomination for Best Female Pop Vocal Performance. Its music video, in which she parodies celebrities such as Lindsay Lohan, Jessica Simpson, Mary-Kate Olsen, and Paris Hilton, won the MTV Video Music Award for Best Pop Video. Subsequent singles "Who Knew" and "U + Ur Hand" were substantial hits in Australia and Europe, and they later became top ten singles in the U.S. in 2007. The non-U.S. singles were "Nobody Knows," a minor hit in the UK, Australia and Germany; "Dear Mr. President," an open letter to American President George W. Bush (featuring the Indigo Girls) and a number 1 hit in Belgium, a top five hit in Germany, Australia and other countries; "Leave Me Alone (I'm Lonely)", a UK top 40 and Australian top five entry; and "'Cuz I Can".

The album has sold over 1.3 million copies in the U.S., over 700,000 in Australia, and 6 million worldwide. Proving very popular in Australia, with 6 top five singles, and a record breaking 62 weeks in the top 10, so far the album has gone 10 times platinum. Even as of June 2008, the I'm Not Dead album returned to the Australian Top 40 ARIA charts and remained there in November 2008 where it sits at number 15 on the chart - a total of 110 weeks in the Australian top 40 to date. In June 2009 the album returned once again to the Australian top ten album charts in its 142nd week in the national top fifth.. It re-entered at #10 on the back of her mammoth Funhouse Tour.

In support of the album, Pink embarked on the world I'm Not Dead Tour, for which ticket sales in Australia were particularly high; she sold approximately 307,000 tickets in Australia, giving her the record for the biggest concert attendance for an arena tour by a female artist.

One of the London shows on the tour was taped and released as a DVD, Pink: Live from Wembley Arena. In 2006, Pink was chosen to sing the theme song for NBC Sunday Night Football, "Waiting All Day for Sunday Night", which is a take on "I Hate Myself for Lovin' You" by Joan Jett. She contributed a cover of Rufus's "Tell Me Something Good" to the soundtrack of the film Happy Feet, and lent her name to PlayStation to promote the PSP, a special pink edition of which was released.

In December 2007, a special edition Pink Box, which comprises her second to fourth albums and the DVD Live in Europe, was released in Australia and reached the top twenty on the albums chart and was certified Gold, selling over 35,000 units.

On August 7, 2008, Pink's single "So What" was leaked online, and radio stations across Australia were quick to give it massive airplay. Within less than 6 hours from the leak, "So What" was voted #1 on Nova 100 Melbourne and shot to #1 on the Today Network's national radio Hot30 Countdown. It also shot straight to number 1 on the official Australian and British iTunes single downloads charts. On August 22, Pink announced a new track titled "Crystal Ball".

On September 18, 2008, "So What" became the first solo number one of her career on the Billboard Hot 100. The track has also reached number one in United Kingdom, Australia, New Zealand, Canada and Germany.[citation needed.

On October 19, 2008, Pink was the guest of honour at the 2008 ARIA Music Awards held in Sydney, Australia, where she sang "So What". On November 3, 2008, "Funhouse" debuted at number one on the ARIA charts, certified two times platinum and selling over 86,000 units in its first week. Pink's "Funhouse" tour sold out all concerts in Australia, and she will perform a total of 58 shows around the country between May and August 2009, performing for more than 600,000 Australian fans.
