Rihanna 'Acting Out.' Friends Say Chris Brown is Bad News.

So much Chris Brown news this weekend…

The “Think Like a Man” actor and singer split with his ex Karrueche Tran not long ago, saying that he didn’t want his friendship with singer and “Battleship” star Rihanna to hurt her.

Meanwhile Rihanna and Brown appear to be back on and going full-force. The sexy lady has been seen lap dancing and kissing her beau.

Interesting, since Brown keeps getting spotted with Tran… the two met up after the break up, and again on Halloween weekend when Brown split his partying between the two beauties.

But apparently Tran has had enough of Brown’s dangling. She posted new photos to Twitter of herself in the company of a man with his arms around her with the caption "Dynamic Duo."

Meanwhile Rihanna seems to be struggling with her new (unconfirmed but pretty obvious) relationship with the man who punched her face in 2009, resulting in a split. After Rihanna confessed on an Oprah interview that she still loved him, the two were quick to reunite.

But friends of the lady are concerned. They say Rihanna is being eaten up with worry over Brown cheating on her—and if he’s still keeping Tran on the line, she might not be missing the mark with that one.

“His game playing is so confusing for Ri,” a friend of the singer said. “She simple doesn’t understand why he needed to see Karrueche.”

Brown reportedly met back up with his ex originally to “tie up loose ends.” Tran was seen leaving the next morning in the same clothes from the previous night.

“When Chris is messing her around she loses all interest in normal life,” the source added. “She doesn’t look after herself and she acts out. She’s always on edge, texting Chris constantly—it’s like there’s no one else in the world who she’ll listen to.”

Hopefully Chris Brown’s admission that he is trying to be a better person will somehow factor into this soon…
