Beyoncé and Jay-Z may not be talking about their wedding, but her bling certainly seems to be.

Beyoncé happily flashed a whopping hunk of diamond on her left-hand ring finger Tuesday night at her new husband's concert with Mary J. Blige at Atlanta's Phillips Arena.

Wearing a short black dress and big hoop earrings, the newlywed singer sat in a VIP area with buddy Usher. The two leapt to their feet to groove hard when Jay-Z launched into his hit "PSA," with its lyrics, "I got the hottest chick in the game wearing my chain."

Usher threw up the diamond Roc sign, while Beyoncé showed off a telltale diamond rock of her own and waved her arms to the beat.

During the show, Beyoncé also relaxed backstage on a plush red couch, sporting shades and singing along to Blige's songs as Jay-Z made last-minute costume changes.

On Monday night, Jay-Z celebrated without his wife – or a wedding ring – at his 40/40 club in Manhattan, where he cheered during the NCAA men's basketball championship game with friends including rapper Tru Life.

An unlit cigar dangling from his hand, Jay-Z was in a good mood as he coyly evaded wedding questions. "I don't know what you're talking about!" he said with a laugh when congratulated by patrons.
