When it comes to Hollywood romances, they don't get much more turbulent than Rihanna and Chris Brown's.

The on-again off-again couple reportedly split for good last week and have taken to Twitter to voice their mutual contempt for each other.

The music superstars sent out thinly veiled tweets on Thursday and Friday seemingly accusing the other of playing the field while they dated.

Rihanna started it off, uploaded an Instagram picture with the words:

If I drop all my hoes for you and we still don't work out you owe me some hoes.

Breezy then upped the nastiness factor by tweeting:

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

Chris' tweet comes after reports that Rihanna was partying with ex JR Smith on Tuesday after her show in New York.

Things turned sour earlier in the week between the two singers when Chris tweeted: 

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

Less than two hours later,the Bajan beauty replied:

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

Bad girls want a real ni–aaa…. Cuz real ni–az just wanna f*ck. 

Got a thang for a King, but chu ain't a King!!!

Ouch! Things don't look too rosy between the couple...

Seems like Chris followed his dad's advice.These two are like ticking time bomb together.....Its high time for them to move on!
