The romance rages on for Rihanna and Chris Brown, who spent Wednesday night at a Kanye West concert at Spotlight Live, a hip Times Square restaurant, a karaoke bar – and possibly the bedroom!

One day after Rihanna helped Brown celebrate his 19th birthday at a Manhattan club (his actual b-day was May 5) the pair got even more HOT and affectionate in plain view of other concert-goers.

Chris Brown draped his arm around Rihanna, 20, as the two flirted, danced, clapped and sang along to the short concert. As Kanye West left the stage, Rihanna leaned over and planted a big kiss on Brown.

The couple then hung out with some friends in back. An hour after the concert, music’s smoldering new couple retreated out the back door, posing for pictures – but only separately.

Chris Brown and Rihanna both stopped when fans asked to take photos with them, but they declined to be photographed together.

Although they’ve been spotted hooking up from Les Deux to Europe to the Caribbean – including a romantic vacation in Jamaica in February – Brown and Rihanna won’t publicly confirm their love.

Earlier this month, Rihanna shared the most information yet when she told Elle Magazine that she and Brown had become “very close.”
