The 24-year-old strikes a variety of sexy poses and showed plenty of flesh but she was not so keen on revealing anything about her on/off relationship with Chris Brown.

The Bajan beauty, who likes to share images aplenty with her fans, chatted happily about how to take the perfect Instagram picture but balked when the interviewer brought up Chris, 23, who she has once again started dating.

She even recorded the track Nobody's Business with him for the album, despite the fact that he's still on probation for assaulting her in 2009.

But the Umbrella songstress then got up to leave the interview:

‘It’s a fun record that The Dream wrote and we loved the lyrics. You’re still asking me questions about it so clearly you don’t know.’

She may have good reason to be a little crabby about the subject of She is said to have fallen out with Brown recently and she seemingly vented her frustration in a post on Twitter.

She wrote: 'Boys will be boys!!! Cause they can’t be men.'
