Michelle, who starred in last year's series of The Big Reunion, was pictured as she walked the red carpet at London's O2 Arena on Wednesday evening (22 January).
Showing off her growing tummy in a floor-length pink gown, Michelle looked gorgeous as she posed for the bank of photographers.
Before hitting the red carpet, she tweeted: "Soooo excited ..Me & @hughhanley in the car waiting in a que to get out at the @OfficialNTAs red carpet! #scary #dontfall #bumpouttoplay lol (sic)."
Michelle is expecting her second child with husband Hugh Hanley in March, but it's clear she's not ready to put her feet up and relax at home just yet!
Earlier in the day, Michelle visited a beauty salon to have her make-up professionally applied ahead of the showbiz bash.
During her car journey home, the Liberty X star took a selfie before uploading it to Twitter.
Alongside the snap, Michelle thanked her make-up artist: "Thank you so so much for making me feel pretty for 2nite #ntas," she said.
Singer Michelle - who underwent a double mastectomy in 2012 in an attempt to beat cancer - announced her pregnancy last September and has since confirmed she's having a baby boy.
