Kelly Rowland has reportedly become engaged to her long term boyfriend and manager Tim Witherspoon. 

The 32-year-old Destiny's Child star has been extremely tight lipped on her relationship, but according to friends of the couple, the pair have been together for several years.

And now it seems they are ready to walk down the aisle, as Kelly has been spotted out and about in Beverly Hills sporting a huge diamond ring.

Rumours have been floating about for several weeks now that Kelly and her beau where set to wed and the first indication that this was true came when Kelly showed off her new piece of jewellery on an Instagram video of Kelly wishing a friend a happy birthday. 

A source told Us Weekly that Kelly is engaged, but is not quite ready to speak publicly about it yet.

They said: 'She has been showing it [engagement ring] off to friends and family and is very happy.

"She wants to enjoy [the engagement] and celebrate for a bit longer."
