Perry provided backing vocals on Mick Jagger's song "Old Habits Die Hard", which was included on the soundtrack to the 2004 film Alfie. Perry worked with songwriters including Desmond Child, Greg Wells, Butch Walker, Scott Cutler, Anne Preven, the Matrix, Kara DioGuardi, Max Martin, and Dr. Luke. Ballard then introduced her to Tim Devine, an A&R executive at Columbia Records, and she was signed as a solo artist.
Perry and her longtime partner and actor Orlando Bloom, with whom she shares 5-year-old daughter Daisy Dove, announced their split in July. Trudeau, who resigned as Canadian prime minister earlier this year amid a dismal election forecast, split from his wife Sophie Grégoire in 2023. In one clip, Trudeau – wearing a casual black T-shirt, a difference from the suits of his decadelong tenure as the 23rd prime minister of Canada – held onto a railing while watching Perry solo.
In February 2017, the singer launched a shoe line titled Katy Perry Collections. Its third single, "Swish Swish", featured Nicki Minaj and followed the next month. The song reached number one in Australia and number eleven in the United States. Perry chose to release it as a standalone track rather than save it for her album "because now more than ever, there is a need for our world to unite". She described it as "the most fun, colorful world that helps guide your musical dreams".
"Wide Awake" was released glitzbets casino login on May 22 as the re-release's second single, peaking at number two on the Billboard Hot 100 and number one in Canada and New Zealand. On September 7, she set a new record by becoming the first artist to spend 69 consecutive weeks in the top ten of the Hot 100. It topped the Billboard Hot 100 for five non-consecutive weeks, making Teenage Dream the ninth album in history to produce four number one singles on the chart. "E.T." featuring Kanye West was released as the fourth single from Teenage Dream on February 16, 2011. She also served as a guest judge on British The X Factor later that month before releasing the album's second single, "Teenage Dream", in July.
Perry embarked on her second tour, the California Dreams Tour, in support of Teenage Dream from February 2011 to January 2012. On January 5, 2012, Perry was named the sixth best-selling digital artist in the United States, with sales of 37.6 million units according to Nielsen SoundScan. For this record, she received an honorary American Music Award in November 2011 and another Guinness record. It became the album's third consecutive number one on the Billboard Hot 100 on December 8, 2010. It has since sold over 12 million copies worldwide, being her highest-selling album to date. Released on August 24, 2010, Teenage Dream debuted at number one on the Billboard 200, and received mixed reviews from music critics.
That year, Perry also appeared in the music video for "Learn to Fly" by Carbon Leaf, and she played the love interest of her then-boyfriend, Gym Class Heroes lead singer Travie McCoy, in the band's music video for "Cupid's Chokehold". Some of the material from Fingerprints that did not make it on One of the Boys was given to other artists, such as "I Do Not Hook Up" and "Long Shot" to Kelly Clarkson, and "Rock God" to Selena Gomez & the Scene. Perry would also perform at the Hotel Café, performing new music while she was between record labels.
Perry has described herself as a "singer-songwriter masquerading as a pop star" and maintains that honest songwriting is very important to her. One of the Boys is a pop rock record, while Teenage Dream features disco influences. Before she began incorporating elements of pop, rock, and disco into music, Katy Hudson contained gospel. Perry cites Alanis Morissette and her 1995 album Jagged Little Pill as a significant musical inspiration.
The record was panned by critics, and Perry was widely criticized for her decision to work with Dr. Luke on it after singer Kesha's allegations of sexual assault against him. In February 2024, Perry announced her exit from American Idol following the conclusion of the twenty-second season, saying she wanted to "go out and feel that pulse to my own beat" and release new music after being "in the studio for a while". Four months later, she sold her music rights to Litmus Music for an estimated $225 million.
That month, a portrait of Perry by artist Will Cotton was included in the United States National Portrait Gallery. On June 26, 2014, she was declared the Top Certified Digital Artist Ever by the Recording Industry Association of America (RIAA) for certified sales of 72 million digital singles in the United States. Her performance was critically acclaimed, and Guinness announced two days after the singer's halftime show that it garnered 118.5 million viewers in the United States, becoming the most watched and highest rated show in Super Bowl history. On November 23, 2014, the National Football League (NFL) announced that Perry would perform at the Super Bowl XLIX halftime show on February 1, 2015. Perry's third headlining tour, the Prismatic World Tour, began in May 2014 and concluded in October 2015.
As of September 2025, she was the second-most followed woman on the site, with over 104 million Twitter followers, and the sixth most followed musician across social media with a combined total of over 377 million followers across Facebook, Instagram, and Twitter. Keith Caulfield of Billboard stated that Perry is "the rare celebrity who seems to have enormous popularity but genuine ground-level interaction with her adoring KatyCats". She received a Guinness record for most Twitter followers, and became the first person to gain 100 million followers on the site in June 2017. Darren Harvey of musicOMH compared Perry's vocals on One of the Boys to Alanis Morissette's, both possessing a "perky voice shifting octaves mid-syllable". Lyrically, the album addresses relationships, self-reflection, and everyday life.
During May 2024, it reached four billion views, making it the most viewed music video by a female artist on YouTube at that time. In the United States, she has accumulated nine number-one singles on the Billboard Hot 100, her most recent being "Dark Horse", and holds the record for having 18 consecutive number-one songs on the Billboard Dance Club Songs chart. Throughout her career, Perry has also co-written songs recorded by other artists, including Lesley Roy, Kelly Clarkson, Jessie James Decker, Selena Gomez & the Scene, Britney Spears, Iggy Azalea, Rita Ora, Nicki Minaj, and Ariana Grande. On June 15, 2017, Calvin Harris released a song titled "Feels" from his album Funk Wav Bounces Vol. The Matrix's self-titled album, which Perry had recorded with the band in 2004, was released on iTunes on January 27, 2009, as a result of her solo success.
She also recorded the song "Immortal Flame" for the game Final Fantasy Brave Exvius, and had a playable character modeled after her. The following month, she released another fragrance with Coty, entitled Mad Potion. Outside of her music career, Perry reprised her role as Smurfette in The Smurfs 2, which was released in theaters on July 31, 2013. Ferras was the first artist to get signed to her label, and Perry served as an executive producer on his self-titled EP.
