Listen to Kelly Rowland on iHeartRadio

(Yahoo!) - Kelly Rowland might have some explaining to do!

The "X Factor" judge debuted a gorgeous ring on her that finger in a recent Instagram video, leading us to believe that she may have accepted a proposal from her rarely seen boyfriend and manager, Tim Witherspoon.

Last month, the former Destiny's Child singer told E! News that she was "too busy with the career" to get married, but this new piece of bling might suggest otherwise.

In the Nov. 15 video, Rowland is wishing her songwriter-producer pal Patrick "J Que" Smith's kiddo a happy birthday. At the end, she goes to blow him a kiss and winds up revealing a giant sparkler.

Reps for Rowland have not yet responded to omg!'s request for comment.

One day after the video was posted, the 32-year-old songbird took to Twitter and shared lyrics from her Destiny's Child song "Happy Face."

Could the tweet have been a secret message about her new title as a fiancée?

Rowland definitely keeps a low profile when it comes to her personal relationships. She and Witherspoon, who have been rumored to be dating on and off over the past four years, are rarely seen together. She was previously engaged to former NFL star Roy Williams in 2004, but the two never tied the knot.

Keeping her life shrouded in privacy doesn't mean a wedding is not in the works. Many Hollywood stars have remained tight-lipped on their love affairs and then shocked us with surprise weddings and engagements, much like Kerry Washington did this summer.

Hopefully, Rowland's new rock and cryptic tweet means she's no longer a single lady!
