[1] Her first solo studio album, Can't Take Me Home (2000) was released to commercial success and received double platinum certification by the Recording Industry Association of America (RIAA).

Pink gained further recognition for her 2001 collaborative single "Lady Marmalade" (with Christina Aguilera, Missy Elliott, Lil' Kim and Mýa), which was released for the Moulin Rouge!

Pink shifted to pop rock with her second studio album, Missundaztood (2001), which sold over 13 million copies worldwide and yielded three top ten singles: "Get the Party Started", "Don't Let Me Get Me", and "Just Like a Pill".

[41] In 2001, Pink, alongside singers Christina Aguilera and Mýa as well as rapper Lil' Kim, performed a cover of "Lady Marmalade" for the soundtrack of the film Moulin Rouge!.

[44] Tired of being marketed as another cookie cutter pop act, as well as eager both to be seen as a more serious songwriter and musician and to perform the type of music she wanted to, Pink took her sound in a new direction and sought more artistic or creative control during the recording of her second album, Missundaztood.

[47] Perry co-wrote and co-produced the album with Dallas Austin and Scott Storch, and according to VH1's Driven program, Antonio "LA" Reid of LaFace Records was not initially content with the new music Pink was making.

It also became a worldwide hit, reaching number one in Australia, Ireland, New Zealand, Romania, and Spain, as well as spending four weeks at the top of the European Hot 100 Singles chart.

[54] In mid-2003, Pink contributed the song "Feel Good Time" to the soundtrack of the film Charlie's Angels: Full Throttle, in which she had a cameo appearance as a motocross race ramp owner/promoter.

Featuring electronic music artist William Orbit, it became Pink's first single to miss the top 40 on Billboard's Hot 100 chart, although it was a hit in Europe and in Australia.

"[55] Pink worked with producers Max Martin, Billy Mann, Christopher Rojas, Butch Walker, Lukasz Gottwald, and Josh Abraham on the album.

The album's lead single, "Stupid Girls", was Pink's biggest US hit since 2002 and earned her a Grammy Award nomination for Best Female Pop Vocal Performance.

[58] 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.

Released in September, The Truth About Love made its debut atop the Billboard 200 with first-week sales of 281,000, making it her first number-one album in the United States.

It became the most successful single from The Truth About Love, topping the record charts in more than 20 countries worldwide and becoming Pink's fourth number-one hit on the Billboard Hot 100.

[119] The following July, it was announced that Pink had written a song for French-Canadian singer Celine Dion called "Recovering" for inclusion on her upcoming English-language album.

[135][136] On October 23, 2018, Pink released her version of the song "A Million Dreams" from the upcoming "The Greatest Showman – Reimagined" album, a reworking of the soundtrack with contributions from various artists including Kelly Clarkson, Kesha, Jess Glynne and Missy Elliott.

[139][140] On the release date, Pink performed the song alongside a medley of her biggest hits at the BRIT Awards, including "Try", "Just Give Me a Reason", with fun.

[150] Later that year, she attended the Taylor Hawkins Tribute Concert in Los Angeles, performing "Barracuda" by Heart, "Somebody To Love" by Queen and "The Pretender" by Foo Fighters.

[185] Aside from her music, Pink has been noted for her fashion style, such as her "adventurous" hairstyles, which have ranged from fluorescent spikes to pink-streaked dreadlocks to a pitch-black skater cut.

[191][192][193][194][195] In December 2015, Pink was appointed as a UNICEF Ambassador and the agency's Kid Power National Spokesperson to help raise awareness about its lifesaving health and nutrition programs around the world.

[197] QR codes for UNICEF USA were placed at all merchandise stands, which directed fans to purchase basic necessities and school supplies for children in need.

[200] Pink and Kelly Clarkson helped raise $60,000 for No Kid Hungry and Sweet Relief Musicians Fund by auctioning off "one-of-a-kid" art pieces depicting their songs in sound waves.

[207] In July 2021, she offered to pay the fines handed out to the Norwegian women's beach handball team after they wore shorts like their male counterparts instead of bikini bottoms.

[226] The singer partnered with REVERB on her Beautiful Trauma Tour to reduce its environmental footprint and empower fans to support her work with UNICEF and No Kid Hungry.

[243] In January 2023, the singer's endorsement was featured in a Pfizer commercial alongside Questlove, Jean Smart, and Michael Phelps, as part of a campaign to remind the public of the availability of COVID-19 products.

"[166] Ann Powers refers to her as a "powerhouse vocalist", stating her mix of rebellion, emotional rawness, humor, and "infectious" dance beats created "a model for the mashup approach of latter-day divas such as Katy Perry, Kesha, and Rihanna.

[245] Entertainment Weekly said: "She essentially invented the whole modern wave of Pop Diva Domination: You can draw a straight line from "Get This Party Started" to Katy Perry, Kesha, pre-messianic Lady Gaga, and post-weird Rihanna.

"[246] Glamour Magazine wrote: "When Pennsylvania-born Alecia Moore debuted in 2000, pop was dominated by long-locked blonds like Britney Spears, Christina Aguilera and Jessica Simpson.
