Beyonce, Blake Lively Sparkle at Lorraine Schwartz Launch (PHOTOS)

Beyonce and Blake Lively joined a bevvy of blinged-out beauties at the launch of jeweler-to-the-stars Lorraine Schwartz’s new “2BHappy” collection in New York Monday night.

White-hot host Beyonce mingled with pal Mary J. Blige and the ever-sexy Kim Kardashian at Lavo. All of the ladies sparkled in Schwartz earrings, bangles and other ice. As chummy as the gals seemed with each other, they proved diamonds really might be a girl’s best friend!
