Rihanna, Chris Brown fighting on Twitter over break-up

'R&B' star Rihanna and her rapper boyfriend Chris Brown have been fighting on micro-blogging site Twitter and have accused each-other of cheating.
The 25-year-old's boyfriend recently announced their split on an Australian radio show, reported Daily Mirror.
Both the singers have been tweeting and posting nasty messages on instagram against each other for cheating in the relationship.
Rihanna started the row by a picture with the message, "If I drop all my hoes for you and we still don't work out you owe me some hoes."
Brown then retaliated on Twitter by posting, "She's not mine if she's everybody else's".

Earlier he had tweeted, "Sometimes loving someone is too much! So loving from a distance will help everyone grow! Be blessed. Live ya life!"
Rihanna again hit back with a tweet that suggested Brown had been less than faithful.
"Settling is not an option! Nothing less than 100 per cent loyalty, honesty, and respect! Love ain't for kidz," she wrote.
