2010–2012: Teenage Dream and marriage
After serving as a guest judge on American Idol, Perry released "California Gurls" featuring Snoop Dogg on May 7, 2010. The song was the lead single from her third studio album, Teenage Dream, and reached number one on the Billboard Hot 100 in June. 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. "Teenage Dream" reached number one on the Billboard Hot 100 in September. Released on August 24, 2010, Teenage Dream debuted at number one on the Billboard 200, and received mixed reviews from music critics. It has since sold over 12 million copies worldwide, being her highest-selling album to date. Teenage Dream would go on to win the 2011 Juno Award for International Album of the Year. In October, "Firework" was released as the album's third single. It became the album's third consecutive number one on the Billboard Hot 100 on December 8, 2010.
"E.T." featuring Kanye West was released as the fourth single from Teenage Dream on February 16, 2011. 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. "Last Friday Night (T.G.I.F.)" followed as the fifth single in June, and Perry became the first female artist to achieve five number-one Billboard Hot 100 songs from one album when the single topped that chart on August 17, and the second artist after Michael Jackson with his album Bad. For this record, she received an honorary American Music Award in November 2011 and another Guinness record.
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. Following the October release of "The One That Got Away" as its sixth single, Teenage Dream became the third album to produce six top-five songs on the Billboard Hot 100. It joined George Michael's Faith and Janet Jackson's Rhythm Nation 1814; the latter remains the only album to ever achieve seven top-five entries. The song peaked at number three in the U.S. and number two in Canada.
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. That month, she became the first artist to have four songs sell over 5 million digital units when "E.T." reached that mark along with "Firework", "California Gurls", and "Hot n Cold". On February 13, Capitol released the lead single from Teenage Dream: The Complete Confection, "Part of Me", which debuted at number one on the Billboard Hot 100 and became Perry's seventh single overall to top the chart. Teenage Dream: The Complete Confection was released on March 23, and serves as a reissue of Teenage Dream. "Wide Awake" was released 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.
Perry embarked on her second tour, the California Dreams Tour, in support of Teenage Dream from February 2011 to January 2012. The tour grossed $59.5 million globally and won her the award for Best Live Act at the 2011 MTV Europe Music Awards. On September 23, 2011, she performed on the opening day of the 2011 Rock in Rio festival along with Elton John and Rihanna. In September 2010, Perry was scheduled to appear on the 41st-season premiere of Sesame Street. After her scene was uploaded to YouTube, viewers criticized Perry's exposed cleavage. Four days before the scheduled airing, Sesame Workshop announced that the segment would not air on television, but would still be available to watch online. Perry subsequently mocked the controversy on Saturday Night Live, where she was a musical guest and wore an Elmo-themed shirt showing large amounts of cleavage during one skit.
In December 2010, Perry played Moe Szyslak's girlfriend in the live-action segment from a Christmas episode of The Simpsons titled "The Fight Before Christmas". Two months later, she made a guest appearance on the How I Met Your Mother episode "Oh Honey", playing a woman known as Honey. The latter role won her the People's Choice Award for Favorite TV Guest Star in January 2012. She made her film debut in the 3D family motion picture The Smurfs as Smurfette on July 29, 2011. The film was a financial success worldwide, while critics gave mostly negative reviews.
She hosted Saturday Night Live on December 10, 2011, with Robyn as the episode's musical guest. Perry's work on the episode received generally positive reviews from critics, who praised her performance in the episode's digital short featuring her and Andy Samberg. In March 2012, she guest starred as a prison security guard named Rikki on the Raising Hope episode "Single White Female Role Model". On July 5, 2012, Perry's autobiographical documentary Katy Perry: Part of Me was released to theaters through Paramount Pictures. The film received positive reviews and grossed $32.7 million worldwide at the box office.
Perry began to venture into business when she endorsed the fragrance, Purr, in November 2010. Her second endorsed fragrance, Meow!, was released in December 2011. Both perfumes were released through Nordstrom department stores. Electronic Arts recruited her to promote their new expansion pack for The Sims 3: Showtime, before releasing a separate stuff pack featuring Perry-inspired furniture, outfits, and hairstyles, titled The Sims 3: Katy Perry's Sweet Treats, in June 2012. The following month, she became the spokesperson and ambassador for Popchips and made an investment in the company. Billboard dubbed her as their "Woman of the Year" for 2012.
She married Russell Brand on October 23, 2010, in a traditional Hindu ceremony near the Ranthambhore tiger sanctuary in Rajasthan. On December 30, 2011, Brand announced that they were divorcing after 14 months of marriage. Perry later stated that conflicting career schedules and his desire to have children before she was ready led to the end of their marriage and that he never spoke to her again after sending a text message that he was divorcing her, while Brand asserted that he divorced her due to her commercial success and reluctance to engage in activism. She was initially distraught over their divorce and said that she contemplated suicide. Since they married without a prenuptial agreement, he was eligible to claim half of the estimated $44 million she earned during their marriage, but declined. Perry began a relationship with singer John Mayer in August 2012, the year her marriage with Brand had ended.
