"I do miss [Chris Brown]" - Rihanna opens up to Oprah

In a newly-released teaser of Rihanna's upcoming interview with Oprah Winfrey, the singer admits that she still 'misses' her ex [Chris Brown].

The Barbadian pop star revealled: 'I'm reminded by a lot of things. A lot of good memories we had.'

'By the slightest things; hotel rooms, tour venues, any little thing, music, songs, and I do miss him at times.'

In the clip, shot for Oprah's Next Chapter, the 58-year-old presenter revealed the Umbrella singer 'talks a lot, a lot, a lot about you know who, Mr. Chris Brown.'

Rihanna's turbulent two-year relationship with the recent Grammy winner ended after he assaulted her the eve of the 2009 Grammy Awards; and Brown was sentenced to five years probation and six months of community labour.

Brown and his lawyer Mark Geragos are currently fighting a $16million lawsuit filed by Entertainment Enterprises this week alleging that the hip-hop star and Drake caused the W.i.P. bar brawl which left several injured in June.

It is believed the violent row erupted over the artists' alleged relationships with Rihanna.
