Rihanna and Chris Brown walked away empty-handed from the Grammy Awards at L.A.’s Staples Center on Sunday (Feb. 10) -- but the on-again couple still felt like total winners in one another’s company.

During the evening of lively performances, Brown, 23, noticeably failed to join the audience in numerous standing ovations for the likes of Carrie Underwood, Kelly Clarkson and his nemesis Frank Ocean.Notes one observer to Us Weekly: "The only time Chris Brown stood up the entire show was during Rihanna’s two performances (her powerful ballad "Stay,” and during a tribute to Bob Marley). Otherwise, he stayed seated.” Indeed, although Brown and Rihanna, 24, didn’t walk the red carpet together, they happily posed for several photos together inside the auditorium -- with Rihanna, clad in a stunning red Azzedine Alaia gown, cuddling with her man, wearing a white Lanvin suit.
