Kelly Rowland has sparked speculation that she could be expecting her first child.

The former Destiny's Child singer showed a hint of a baby bump when she peformed at the 'Rhythm On The River' music festival over the weekend wearing a crop top and high wasted baggy trouser combo.

The R&B star, known for her washboard abs and revealing outfits, stepped out on stage covered up and appearing more curvey than before, setting tounges wagging.

It was only last month that we were congratulating to Rowland after she secretly wed her long-time boyfriend/manager Tim Witherspoon and now there are whispers that she may have another big announcement soon.

The very private celebrity at the time kept the details of the wedding top secret and only broke the news of her engagement when asked on Queen Latifah's talk show.

"He put a ring on it. Yes, it's official," she told the popular host. "It's been a while... we've kept it very very low for years, to be completely honest."
