Rapper Chris Brown has been 'having fun' with R&B star Rihanna but insists their relationship is nothing serious.
The 25-year-old 'Fine China' singer, who has an on-off relationship with model Karrueche Tran, said his relationship with his former girlfriend Rihanna is nothing 'serious' and they're just enjoying each other's company at the moment, reported Contactmusic.
"We're friends. Nothing too serious... We're not trying to start a life together right now, we're just having fun," Brown said.
It is believed 'Drunk Texting', a track on Brown's new album 'X', is about Rihanna.
