The Destiny's Child star is expecting her first child and has adjusted her workout regime to take account of her pregnancy.
Today, she uploaded a photo to Instagram showing her doing exercises with a personal trainer.
Check out the baby bump!
Kelly wore a sports bra and leggings in the image, giving us a full view of her blossoming bump.
Another picture showed the 'Survivor' singer hard at work on the treadmill with a couple of pals.
As well as working up a sweat in the gym, the star has been doing yoga during her pregnancy, sharing a photo last week of her looking peaceful while striking a pose.
This will be Kelly's first child.
Her pregnancy news was announced shortly after she married partner Tim Witherspoon in a secret Costa Rican ceremony attended by Destiny's Child bandmates Beyonce and Michelle Williams.
