Ooops! Did Kelly Rowland unknowingly spill the beans on an engagement?

K. Row has always kept her love life secretive, even though she’s recently dished she’s currently in a relationship with a lucky mystery man. But are the couple headed down the isle?

While wishing the son of friend/producer-songwriter Patrick "J. Que" Smith a happy birthday via Instagram, Rowland blew him a quick kiss with her left hand, which just so happened to have a large, glistening rock planted on her ring finger.
