Showing off: The 30-year-old star flaunted her assets in a burgundy thong bikini 

She sported a very tiny burgundy bikini while enjoying a break with her NFL player husband Jay Cutler. 

It's been a rough month in the Cutler household, so it's little wonder why they decided to escape on a tropical holiday.

Just weeks after Jay was dropped from the Chicago Bears football team, the former quarterback and his lady packed their bags and headed off on a beach vacation.

The former Laguna Beach star shared a series of photos from their picturesque getaway on Instagram over the weekend.
