Ultra-sexy Julianne Hough wasn't letting her ex-boyfriend Ryan Seacrest ruin her 4th of July celebrations! While Seacrest was out with a new lady-friend, Julianne posted a picture of herself posing in an American flag towel, and not much else!

The 24-year-old Hough, posted the above photo on Instagram with this caption, ""#tbt Happy 4th of July!!! :)" #tbt stands for Throw Back Thursday, which makes sense since this photo was from a photo shoot in 2008.

Hough caught some flack from her Instagram followers who commented that it's not appropriate to wear the American flag -- little did they know, this is a beach towel made to look like the American flag. We get where they're coming from, respecting the flag is a priority!

One of Julianne's Instagram followers decide he'd take a stab at her sexy pose -- it's close, but we prefer Julianne's photo.
