And, as usual, the former Coronation Street actress dressed to kill.
Michelle wore a sexy tuxedo dress (from her own Lipsy London collection) in black and white with black buttons, which just about managed to keep her famous curves contained.
Looking tanned from top to toe, she wore her long brunette hair loose and tousled, and teamed the outfit with perfectly matching gold, white and black heels.
The actress, who celebrated her actual birthday on 3 June, spent the night with eight of her closest girlie friends at South African restaurant Shaka Zulu in Camden, London.
While Mark Wright might have been pining for his beautiful fiancée, Michelle was all smiles during the night - and even took to the DJ booth for a few cheeky spins.
Before heading out for her big night, she tweeted: "Arrived in London with ma girls ! Looking forward to @ShakaZuluLondon #excited #birthday."
It's been an emotional week for Michelle after her character Tina McIntyre was killed off in Corrie.
She also launched her own clothing range with Lipsy, her first ever fashion collection.
