I swear, if that Kimberly Caldwell broke my David Cook's heart, girl's going to have some 'splainin' to do.
Star mag says that Kim was seen getting wasted, dirty dancing, and making out with Ryan Der at ONE Sunset in Los Angeles on Dec. 29.
"Everyone could see she was really letting loose," an insider blabbed. "She and Ryan were laughing together as they threw back beers and vodka cocktails." Soon after, the couple were reportedly "grinding on the dance floor. They started playfully kissing, but that quickly led to long lip locks until they were full-on making out."
Poor David! He can come over and I'll make it all better.
