The pop star will be debuting her new song, "Wide Awake," written for her upcoming film Katy Perry: Part of Me, live on the BBMA stage.

Previously announced performers include Chris Brown, Justin Bieber, Carrie Underwood, LMFAO, CeeLo Green, Kelly Clarkson, Usher, The Wanted, Linkin Park and Nelly Furtado.

In 2011, Perry became the only woman in history to earn five No. 1 singles on the Billboard Hot 100 chart from the same album. Her Teenage Dream set spun off the No. 1 Hot 100 hits "California Gurls" (featuring Snoop Dogg), the title track, "E.T." (featuring Kanye West), "Firework" and "Last Friday Night (T.G.I.F.)." She nabbed another No. 1 this year, with "Part of Me," the first single from the special edition album Teenage Dream: The Complete Confection.

The Teenage Dream album debuted at No. 1 on the Billboard 200 chart in 2010 and has sold 2.2 million copies in the U.S. according to Nielsen SoundScan.

2011 was a banner year for the singer, as she was also the most-played artist on the radio according to Nielsen BDS (with 1.5 million detections of her songs registered on all formats) and had three of the top 10 most-played songs of the year ("E.T.," "Firework" and "Last Friday Night"). She was also the top selling artist of 2011 in terms of digital track sales, according to SoundScan, with 15.2 million sold. Last year, her "E.T." collabo with West was 2011's third-biggest selling digital song in the U.S., with 4.8 million sold. Collectively, her career digital song sales in the U.S. stand at 41.3 million.

Additional acts will be announced in the coming days.
