Fitness Model Jen Selter Bares Famous Ass for 4th of July Beach Day


Jen Selter is a true patriot when it comes to 4th of July -- just check out her red, white and blue thong and bikini ... and don't forget her ass.

The famous fitness model hit the beach for the holiday weekend, and even under gloomy skies ... she still sizzled next to the ol' American flag. A banging bod will do that sometimes.

Looks like Jen even brought her pup along for some of the beach fun. But who are we kidding ... you probably didn't even notice it was there.
