Holy. Cow. We now have proof that Chris Brown and Rihanna are in contact:
He wished her a Happy Birthday on Twitter and she said thank you! OMFG!
Right around midnight this morning, Brown took to his Twitter to write "HAPPY BIRTHDAY ROBYN!" - Robyn Fenty being Rihanna's real name - to the birthday girl.
Rih, who was physically assaulted by Chris in 2009, but has since warmed up to the star again to some degree, responded "Thanks!" and re-tweeted the message.
No doubt about it, girl's friendly with her ex again.
While Chris attended her b-day bash last week, there's no proof of them together since his peeps slapped anyone with a camera with a confidentiality agreement.
He didn't want pics of him with her to get out, but evidently has no qualms about sending along a public Twitter birthday wish, and she has no problems responding.
The restraining order against Chris has been lifted, so this isn't shady at all.
The birthday message comes as rumors continue to swirl about the two collaborating on a remix for one of their new singles ... fittingly called "Birthday Cake."
Rihanna turns 24 today. Chris, who is still dating Karrueche Tran (and living with her, we're told) despite the Rihanna romance rumors, will be 23 in May.
Still, we ask: Should Rihanna and Chris get back together?
