Kelly Rowland was spotted out getting coffee this week (Nov 27) and there's a huge diamond ring on her hand!

US Weekly reports that she's going to marry her manager Tim Witherspoon and she's uber excited.

Sources told US Weekly and Kelly Rowland can't stop showing the ring off to family and friends. There isn't a rush on setting up wedding arrangements because Kelly wants to "enjoy [it] and celebrate a bit longer."

Go 'head girl, get yourself a man!
