While the rest of us were wolfing down hamburgers on the 4th of July, former Grey's Anatomy star Katherine Heigl (Izzie Stevens) was busy looking perfect in a cute bikini while celebrating the holiday with her family.

Katherine tweeted the photo to the right on the 4th, writing, "Happy 4th of July to all those celebrating today! Xoxo the Kelley's!!" And we must say, she is looking as hot as ever. Plus, it looks like she's having a blast!

She also shared an adorable image of her husband, singer Josh Kelley, and their daughters Naleigh and Adalaide Marie Hope, writing "Daddy's girls!!! Had a wonderful 4th hope you all celebrating did as well!!"

Awww.
