Chris Brown and Rihanna first began dating in 2008 after a couple of years of being “just friends.” All was well until that fateful night of February 8, 2009 when Chris assaulted Rihanna, leaving her swollen, bruised, and scratched. While many assumed that would be the end of their relationship, it wasn’t. The two reconciled late last year and broadcasted their relationship openly on social media. Now, just days after celebrating his 24th birthday with ex-girlfriend Karrueche Tran in Las Vegas, Chris is announcing that he and Rihanna have once again parted ways.
