Wearing a black sparkly dress, “American Idol” Season 6 winner Jordin Sparks returned to the show Wednesday night and sang “Battlefield”–her latest single off her sophomore album.

The song is co-written and co-produced by OneRepublic’s Ryan Tedder, Sam Watters, Louis Biancaniello and Wayne Wilkins.

Katy Perry also performed during the results show wearing an Elvis bathing suit. Nice outfit! She sang “Waking Up in Vegas”—the fifth single from her platinum selling debut studio album.
