We were surprised that Kris Allen won American Idol.
Still, that wasn't the most unexpected thing to take place on the stage of the Nokia Theatre last night.
As part of the two-hour finale, Kara DioGuardi sang a duet with former nemesis Katrina Darrell! (Remember her? Darrell earned the nickname "Bikini Girl" during the initial rounds of Idol auditions for donning a swimsuit while she sang for the judges.)
Moreover, at the end of their "Vision of Love" rendition, DioGuardi flashed her own bikini body for the world to see.
We strongly recommend watching the duet, if only for Randy Jackson's priceless reaction when Darrell comes out on stage, clearly enhanced in one area of her body.
Compare Kara and Katrina below and then answer our poll question:
Who has the better bikini body?
