The Detroit Lions made some surprise moves during free agency by letting their two star defensive tackles walk and trading for Haloti Ngata from the Baltimore Ravens. One player who has not had anything to worry about is quarterback Matthew Stafford, who was able to watch Detroit's free agency plan unfold from afar.

Of course, Stafford is not the only one that is taking some time to enjoy a vacation right now. Stafford is engaged to be married to Kelly Hall, and she recently took a trip with some lady friends to Las Vegas for a bachelorette party, according to TMZ.

Hall and her friends attended the opening of the MGM Grand's Wet Republic pool and day club, and they were spotted enjoying the sun and warm weather (which is undoubtedly a nice departure from Detroit, which is still emerging from the depths of winter).

Hall and her friends were sporting bikinis and engaging in some cheerleading and crowdsurfing around the pool, among other activities.

Stafford and Hall have been engaged for about a year now, and many remember that they famously (and perhaps oddly) chose to break the news at a Cold Stone Creamery.
