London: Despite being physically assaulted by rapper ex-boyfriend Chris Brown, Rihanna says she decided to collaborate with him to further her career.

The 24-year-old, who had filed a case against Brown in 2009 alleging that he beat her, has teamed up with him for songs 'Birthday Cake' and 'Turn Up the Music', reported  a leading daily.

"I reached out to him about doing Birthday Cake because that’s the only person that really... it made sense to do the record. Just as a musician - despite everything else - that was going to be the person.

"I thought about rappers, and I've done that so many times, and the hottest R&B artist out right now is Chris Brown. So I wanted him on the track," Rihanna said.

But speculation is also mounting that the R&B star may want Brown, 22, back in her personal life too.

Rihanna has been dropping hints on Twitter that the pair may be reconciling. Quoting the Beres Hammond song 'They Gonna Talk', Rihanna tweeted, "When they see me with you, wonder what the crowd would say? When they find us together, what will all the people say?."
