Chris Brown Rihanna Back Together, Couple Step Out Post-Karrueche Tran Split (WATCH VIDEO)

Chris Brown and Rihanna stepped out publicly as a couple for the first time since his public split with girlfriend Karrueche Tran.

The couple attended the launch party for his new fan website, Qubeey, at the Playhouse nightclub in Beverly Hills.

Rihanna was stunning in a white dress, while Brown was casual in a grey hooded sweatshirt. According to an eyewitness, Brown made sure to make the Bajan beauty feel extra special.

"He made her feel like a princess just by the little things he was doing," an onlooker told Hollywood Life. "He opened doors, pulled out her chair, you know, being charming Chris. He was being a gentleman and it was cute. They had a few kisses and some drinks."

Despite the high profile outing, the attendee said the "S&M" singer remained relatively lowkey.

"She loves him and anything she can do to support him she will. She wants to be by his side and show up for him and last night she did."

Brown was rumored to have rekindled his romance with Rihanna after the pair were spotted going on three consecutive dates in New York City earlier this month. The performer released a statement announcing his breakup with Tran to several news outlets after their dates made headlines.

"I have decided to be single to focus on my career. I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna. I'd rather be single allowing us to both be happy in our lives."

After announcing his breakup with Tran on Oct. 4, Brown released a video titled "The Real Chris Brown," where he admitted he was suffering from "loving two people at the same time."

"Is there such thing as loving two people? I don't know if that's possible, but for me, I feel like that. I'm a little drunk, so I'mma be honest ...," he said. "I'm not trying to be a player ... I just care too much sometimes.

"I'm stressed out. When you share history with somebody, then you tend to fall in love with somebody else, it's kinda difficult," he said.

"Wtf is going on?" Tran tweeted after Brown posted his video on Vimeo. "All I'm saying is.. You don't mess with people's genuine feelings. You just don't! Life moves on.. So let's all."

RIhanna recently tweeted a telling message about her relationship with Brown, "Forgiveness wins."

Maximo TV filmed the couple on video cuddling in a private booth at his event. Watch the video of Brown and RIhanna hanging out at his Qubeey launch party in Beverly Hills below.
