The singer, 33, is keeping busy before the imminent arrival - and plans to be fighting fit when she meets her first child later this year.
While lots of expectant mums grab the opportunity to put their feet up while munching on choccie biccies, Kelly is one of an increasing number of celebrities who have worked out throughout their pregnancy.
The Destiny's Child superstar shared a picture of her latest workout with her Instagram followers, with the caption "#sweat".
Kelly looks stunning (and not at all sweaty) as she shows off her growing baby bump in a black gym bra with matching Lycra leggings.
Unsurprisingly, her fans didn't waste any time telling her how amazing they think she looks.
One called her a "sexy mommy", while another simply said "beautiful".
Some fans were a little more concerned however, with one writing: "Take it easy pls@kellyrowland."
Fellow celeb Nicole Polizzi, who has also worked out throughout her pregnancy, was quick to comment, too.
She said: "LOVING how @KELLYROWLAND is staying fit for her pregnancy! Girl let's work out together."
Earlier this month, Kelly revealed she is expecting a baby boy with her new husband Tim Witherspoon.
Back in May, Kelly married Tim in a secret Costa Rican wedding and a month later the couple were headed for baby bliss as Kelly confirmed her pregnancy with a photo of a pair of baby-sized trainers.
