After spending time together holed up in the recording studio, Rihanna may have needed some space from her boyfriend and accused beater, Chris Brown.

The R&B beauty was flying solo as she spent the wee hours of Wednesday morning at Los Angeles nightclub Coco de Ville for a belated 21st birthday celebration—her first public outing since the Grammys-eve incident.

Starting around midnight, the "Disturbia" singer was joined by friends, including Bromance bros Frankie Delgado and Taylor Mosher, on their own private patio. She blew out birthday candles atop pink cupcakes and washed down the treats with complimentary champagne.

A source tells E! News that the starlet "looked good, was smiling and laughing in good spirits upon leaving."

She wore sunglasses as she departed the club around 4 a.m. in a red pickup truck. The source claims her caravan, including the truck, a black SUV and another car, were only followed by a few of the "35-plus paparazzi outside."

As we reported earlier, Rihanna had originally planned to mark her milestone birthday on the real date, Feb. 20, with a bash in Manhattan, but those plans were scuttled in the wake of her blowup with Brown.
