Rapper Chief Keef appears to have confirmed ongoing rumours he's engaged to Pretty Mesha after posting a Twitter.com photo of the model proudly showing off a large diamond rock on her ring finger.

On Monday (13May13), editors at MediaTakeOut.com reported the rising star, real name Keith Cozart, had proposed to his 23-year-old girlfriend, and he appeared to substantiate the claims by re-posting the article on his social networking page and uploading a snapshot of Mesha wearing an engagement ring.

The couple also re-tweeted messages of congratulations, and, when asked by a follower if the news was official, Mesha responded, "Yes!"

No further details were available as Wenn went to press, but 17-year-old Cozart already has two kids, while Mesha has one daughter from a previous relationship.

The hip-hop star is having quite an eventful year - he served 60 days in jail for violating the terms of his probation and was recently ordered to pay child support payments to an unidentified teen, who claims Cozart is the father of her little girl.
