The Coronation Street star, 26, managed to make a simple black suit look sexy as hell when she appeared at Hush nightclub on Saturday night (1 February).
Teamed with a white top, Michelle's only nod to colour was her pastel green earrings and deep rose lipstick - and her glowing tan, of course!
It's no wonder that Michelle's fiancé Mark Wright was missing her during their time apart.
While she was 300 miles away, Mark took to Twitter to post a touching tribute to his actress love.
He said: "How one man can change so dramatically & quickly in one situation in life !! #partyboy to the opposite !! Not ashamed to say it #number1 #MK."
The 27-year-old's sweet message prompted a host of positive responses from his followers, with one fan telling him he was the "luckiest man in the world", to which he responded "too right!"
Mark also revealed he'd asked his brother Josh to be his best man at their 2015 wedding.
Former TOWIE star Mark proposed in October 2013 and has previously spoken about how his relationship with Michelle has transformed his life.
He has said: "I think everyone knows I wasn't the best boyfriend in the world before but this time it's for real."
