Give up your next birthday and bring clean water to people in need

Kelly Rowland's got herself a nice piece of jewelry there.

The singer and X Factor judge ,who told E! News last month that she was "too busy with the career" to consider getting married soon, continued to fuel rumors that she has at least accepted a proposal when she flashed a huge rock while wishing songwriter-producer pal Patrick "J. Que" Smith's kid a happy birthday via Instagram.

When she raised her left hand to blow the child a kiss, there it was, a diamond ring on her wedding finger.

Reps for Rowland have exercised their right to remain silent when it comes to whether the 32-year-old star is engaged or not—but this video isn't going to quash any speculation.

And who might the lucky guy be?

While Rowland has somehow managed to keep her personal life more personal than some celebs, she is said to be dating manager Tim Witherspoon (not to be confused with the boxer of the same name).

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

Rowland was just in Dubai for work, but she's due back in the U.S. this week and has a show with T.I. and 2 Chainz at the Roanoke Civic Center in Virginia on Friday.
