Rebecca Gayheart Plows Through "Rush Hour" Premiere

McSteamy's wife, Rebecca Gayheart, cheerily hit up the "Rush Hour 3" premiere on Monday -- proving there's no bad blood between her and the film's director -- ex-fiance Brett Ratner. *beep beep!*

Now married to "Grey's Anatomy" hottie Eric Dane, Rebecca was previously engaged to Ratner, whom she dated -- for 12 years! Talk about cold feet!

Luckily, their paths crossed last night without accident incident!
