It's Beyoncé!
The star showed off her inked ring finger while hosting the launch party of Lorraine Schwartz's 2BHappy jewelry in NYC, which Kim Kardashian and Blake Lively also attended.
And in true diva fashion, the hostess was three hours late to Lavo for her own party!
We love all of B.'s jewels, but the pointy manicure? Not so much.
