Matt Stafford’s Fiancee — BACHELORETTE PARTY … Suns Out, Buns Out

It’s 48 degrees and gray in Detroit … so Matt Stafford’s wife hit Vegas for her bachelorette have fun — and proved her ass can hang with the best of ‘em!!!

Kelly Hall and her gal pals hit the pool have fun at Wet Republic at the MGM Grand … where she did some bikini crowdsurfing … bikini cheerleading … and other bikini-clad activities — under the 85 degree Vegas sun.

The Detroit Lions quarterback and his the high classes sweetie got engaged last year … and they particularly broke the news at a Cold Stone Creamery.

Now, the wedding is right around the corner — hopefully, the reception will be half as much fun a the bachelorette have fun!!
