Is a Chris Brown Rihanna makeup unfolding? Chris Brown is reportedly winning Rihanna back with renewed effort.

Rumors of a Chris Brown Rihanna makeup sparked when the rapper was spotted attending her concert last week. Rihanna performed with Eminem to a massive crowd at Rose Bowl in Pasadena, California.

The British Mirror quotes a source, "Chris turned up to the second show and watched it from the crowd, but he made his way backstage after the gig was finished to be closer to Rihanna. He was making a huge effort to see her and be seen with her again."

Is Chris Brown on the rebound? Reports claim he's being pulled towards the "Umbrella" singer after a breakup with Karrueche Tran. Pursuing a new relationship might be too early, though, especially with an ex.

Chris appears to be unfazed, according to the source. "He's been texting [Rihanna] loads since he got out of prison last month and she is part of the reason he broke up with Karrueche. He's drawn to her and believes that they're meant to be together."

It's too early for the Jay Z camp to comment on the apparent Chris Brown Rihanna makeup, and Rihanna doesn't seem to be accommodating Chris' efforts at the moment.

Chris' ex Karrueche was quoted in an interview with Keke Palmer last month, on the downsides of dating a celebrity, and goes further by noting Rihanna as an even bigger celebrity.

"I've never dated a celebrity before so it was very new to me, paparazzi and all that. And then, even the situation with Rihanna, you know the reason why people turned into this so much was because it's relatable. I have girlfriends, I have family who's gone through the same situation. It's the case of the ex. We all go through it, [but] in this case my boyfriend is a celebrity whose ex-girlfriend is an even bigger [celebrity]." (yahoo.com)

Is a Chris Brown Rihanna makeup in the works, or will the rapper fall back into the arms of Karrueche (or some other woman)? Considering Chris' erratic history in relationships, it's really anybody's guess.
