Chris Brown has had bitter break ups with his former girlfriends Rihanna and Karrueche Tran in the past. And it now seems like the rapper could be going through another painful heartbreak. The 27-year-old took to social media to rant about cheating girlfriends and this could well be about a mystery woman.

Brown posted two images on his Instagram account, one of which was about why women cheat and how they do it best, while in the other he voiced his frustration on someone who was "playing games".

Bitch playing games when she know you the hottest nigga on the planet!

"We cheat on our girlfriends, but we don't want them to cheat on us...We cheat for sex, just to f**k, but when a woman cheats, she cheats for love and affection. She cheats with a guy that can potentially replace you. We cheat the most, but women cheat the best. We act like its the end of the world when we get cheated on. Women are not afraid to love, commit and be loyal, but the problem sometimes is with us men," read his first post.

In the second post, he shared an image of him performing on stage and captioned it with: "B***h playing games when she know you the hottest n***a on the planet!"

HollywoodLife speculates that Brown's scathing post could be aimed at his rumoured girlfriend Cydney Christine, with whom he was spotted at the Hollywood Horror Nights on 20 October.

Recent reports suggested that Christine and the Royalty album-maker's former girlfriend Karrueche Tran were not on good terms. The former apparently threw shades at the American model, while replying to a fan online. Tran has moved on after splitting from Brown, but reports suggest that Brown still has feelings for her.

"He still calls Karrueche constantly and tries to hook up with her, but she's not down with that at all. Karrucehe has moved on," a source said, according to HollywoodLife.
