The Liberty X singer, 34, bought a touch of Hollywood glamour to Dublin in two different - but equally gorgeous - outfits on her night out with old friend Miss Viviana.
Before the evening began, Big Reunion star Michelle joked that she was about to enjoy an "old bird's night out" and her mission was to "make it until at least midnight".
Dressed in a gorgeous white vintage-style dress with ornate gold top, Michelle looked stunning when she posed on the red carpet of the VIP Style Awards.
She teamed the Piamichi floor-length gown with a simple but pretty clutch and minimal accessories. Deep down, we'd like to think she wore comfortable trainers under the super-glam dress (bet she wasn't though)!
After posing on the red carpet and enjoying a few drinkies at the glitzy event, Michelle then hotfooted it to the RTÉ Television Centre for her appearance on The Late Late Show.
Changing into a gorgeous backless black dress with sequin detail, gym bunny Michelle showed off her fab post-baby figure.
While we think she looks amazing, Michelle is keen to lose more weight after giving birth to son AJ earlier this year.
She later shared a picture of some cheese and onion crisps from her hotel on Twitter, saying: "Ooops raiding the mini bar isn't gonna help me get rid of my baby weight now is it.. Ahh #startonmonday lol ; )."
She also thanked the staff at The Late Late Show for their hospitality and admitted she "can't wait 2get back to my family".
