Did Kelly Rowland get secretly married?

More engagement and marriage rumors have now swirled around the X Factor judge and her producer boyfriend, Tim Witherspoon after she was spotted rocking two different rings on her finger.

A few days ago, Witherspoon uploaded a video to his Instagram account of Rowland saying happy birthday to one of her friend's kids, which she flaunted a huge diamond rock on her finger.

MediaTakeout reported that Rowland was in Dubai on Monday and although she didn't have the big rock on, she was spotted wearing a thinner band, which many assumed to be a wedding band. (See photos here:)

Enstars reported back in September that both Rowland and Witherspoon have matching tattoos. See their tats here:

"Kelly and Tim have been together for years, and decided to get married," a source said. "Kelly wants to keep her sexy singer image alive, so she's keeping everything a secret. Most people didn't even know she had a boyfriend."

Earlier this year, Rowland released the controversial track, Dirty Laundry. She left fans in the dark about whom she was referencing on the song, but admitted that she was in an abusive relationship.

"A piece of me would just go away every time he would say something," she said of the relationship.

Rowland and Witherspoon were spotted leaving a Los Angeles café together last month and have reportedly been seeing each other on and off for four years.
