Looks like Kat Graham was feeling the Cinco de Mayo spirit as she and her fiancé, Cottrell Guidry, went all out for the Mexican holiday!

On Sunday, May 5, the Vampire Diaries actress was spotted out in West Hollywood as she made her way to the Fiesta Cantina restaurant and bar. Donning a giant sombrero and a Spanish-style dress, Kat stopped on the street to pose for a few cute cell phone pics.

Judging by their Twitter updates, it seems like the duo had a phenomenal day full of food and fun! “Started today w/ egg whites,” Cottrell tweeted. “Then a burrito and fried chips w/ cheese sauce, yogurtland, then pizza, then lasagna and ice cream #FatSundays.”

Now all we want to know is: where was our invite?
