Kelly Rowland shows up the cover of the Summer 2012 issue of Vegas Magazine … and to celebrate, the R&B diva hosted a cover party for the issue at Boulevard Pool in Las Vegas Saturday night (Jun 9).

Kelly’s BFF LaLa Anthony was also on hand to help her celebrate the magazine cover, as well as T-Pain, who DJ’d at the party, which also doubled as a 9th anniversary celebration for Vegas Magazine.

Kelly posted a funny picture on Twitter of her, LaLa and T-Pain with the caption, “So busy djing that @tpain doesn’t even know @lala and I are behind him…!!”
