Looks like those rumors are true! After speculation that Rihanna and Chris Brown are getting back together — if Twitter is any indication — it looks like they're reuniting in the musical sense for now.
Rihanna's on the remix of his tune, "Turn Up the Music," and he sings on the remix of her song, "Birthday Cake." As pointed out by USA Today, he Tweeted, "HAPPY BIRTHDAY ROBYN" to the Barbados-born Rihanna, who turned 24 yesterday.
Chris also wrote, "@rihanna goo.gl/ttRJR YIKES!!! Cake, cake, cake!" The link led to Rihanna's "Birthday Cake" remix, which highlights the new Grammy winner as he sings part of the tune.
Rihanna got in to the act, too, and responded by Tweeting, "#RihannaNavy Come and put ya name on it!!!!! "rihanna goo.gl/ttrJR YIKES!!!" Tweets led to more tweets, which all point to the fact they'll collaborate.
She also wrote, "@chrisbrown Turn up the music remix #RihannaNavy #Teambreezy enjoy!!! vimeo.com/mechanicaldumm…"
What do you think about their collaboration — should they stick to music or do you want to see them reunite in the romance department, too? Keep the controversy in mind, considering Chris famously pleaded guilty in 2009 to assaulting his former girlfriend before the Grammy Awards. Sound off below!
