Who says you can't be friends with an ex?!
Rihanna is proving that stigma wrong!
The "Where Have You Been" singer took the time out of her busy schedule to wish her ex-boyfriend Chris Brown a very happy birthday.
Ri Ri took to her twitter and sent him simple wishes, tweeting:
No word on what Breezy has planned for his big 23rd birthday but we're sure his girl Karreuche Tran has some tricks up her sleeve.
Its crazy to think just how far Rihanna and CB have come from their tumultuous past.
Do you guy's think it's okay to be friends with your ex?
