Katy Perry kept things simple as she, dressed in all pink (including her hair and guitar!), took to the stage at the 2011 AMAs last night (Sun Nov 20) in Los Angeles and performed an acoustic version of her latest single “The One That Got Away.”

At the end of her performance, the Pop star was met with a standing ovation, and was also presented with a special award of achievement for scoring five #1 singles from her latest album “Teenage Dream” on Billboard’s Hot 100, an accomplishment only equal to Michael Jackson and his 1987 “Bad” album.
