Brown Splits With Galpal as Rihanna Rumors Abound It's over between Chris and Karrueche Tran By Evann Gastaldo, Newser Staff Posted Oct 4, 2012 1:45 PM CDT 10 comments Comments Singers Rihanna and Chris Brown perform at the Z100 Jingle Ball 2008 at Madison Square Garden on Friday, Dec. 12, 2008 in New York. (AP Photo/Evan Agostini) (Newser) – Rumors of a Chris Brown-Rihanna reunion have been building for months—years, even—but they've really started to ramp up this week. And, conveniently enough, Brown today confirmed it's over between him and girlfriend Karrueche Tran after one year together. "I have decided to be single to focus on my career," Brown tells Us in a statement. "I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna." Sure, Chris, "friendship." Sure. Tran has never been a fan of Rihanna; the two have sparred over Twitter, and Tran was particularly upset when Brown kissed Rihanna on the lips at the MTV Video Music Awards. Sources say Tran has long known Brown is hooking up with Rihanna behind her back. This week, further evidence emerged that a full-fledged Brown-Rihanna reunion is in the cards: Monday night: They were spotted "hugging and kissing" on the dance floor at a New York nightclub, a source tells Celebuzz. Then "they went to the back of the club alone together." TMZ reports that they were in the bathroom together for 20 minutes, and that Brown was later spotted leaving Rihanna's hotel. (He met up with Tran soon after, the New York Daily News reports.) Tuesday night: Brown and Rihanna were spotted at yet another club together, Radar reports; the New York Post adds that they left together. Last night: They attended a Jay-Z concert in Brooklyn, and sources say they were "cuddled up" in the VIP section and "looked full-on back together." But they were "totally casual about it," not "expecting people to be shocked."
