Rihanna and Chris Brown In War Of Words.

The recently split couple are refusing to break up peacefully, tweeting nasty messages to each other about being unfaithful.

                                   

It's not been long since Chris Brown announced he'd split from Rihanna while appearing on an Australian radio station .

But already they've engaged in a battle online, tweeting and instagramming some thinly-veiled digs at each other.

And now the RnB superstars seemed to suggest that there'd been some cheating going on.

And seeing as those pictures of Rihanna kissing a fan surfaced , and Chris was partying with his ex-girlfriend Karrueche Tran , that does seem likely.

The Umbrella singer , 25, started it, uploading this photo to instagram:

                                        

Seeming to imply that she'd ditched her friends while she was with Chris Brown ( like Katy Perry maybe? )

Or it could be that he was unfaithful to her with some hoes.

Chris then retaliated on Twitter, saying:

"She's not mine if she's everybody else's".

Excellent use of the apostrophe there, Chris.

This isn't the first time the ex-couple have used Twitter to write cryptic messages about their relationship.

                                   

Earlier Chris had tweeted the philosophical message:

"Sometimes loving someone is too much! So loving from a distance will help everyone grow! Be blessed. Live ya life!"

Rihanna hit back with a tweet that suggested Chris had been less than faithful:

"Settling is not an option! Nothing less than 100% loyalty, honesty, and respect!! Love ain't for kidz #butimsleeptho"

"Imma do it solo. I mean, at the end of the day, shawty doing her own thang, she on the road."

Chris announced that the couple were over on an Australian radio show.

He said:

“It's always gonna be love. I'm a grown man, just gotta fast forward. I'm always gonna love that person. I cant be focused on wife-ing someone that young."

"I need to be the best Chris Brown I can be.”

And it’s near impossible to keep up with their relationship – which coincidentally is just as on-off as Rihanna’s clothes in those saucy holiday photos.

                                      

The rapper , 24, has already been seen out with other women at The Met Ball and his THREE birthday parties . Greedy.

Meanwhile Ri-Ri's been out shopping in hotpants . And going for dinner in a shirt that's totally undone .

It's classic break-up behaviour.

From the moment they met as teenage sweethearts to break-ups, beat-ups and make-ups - it's the complete timeline of Chris Brown and Rihanna's relationship.

Let's look at them back before they started being mean to each-other on social networking sites:
