The actress, 27, spent Saturday night in Essex helping her fiancé Mark Wright's brother celebrate his birthday.
Alongside Mark, his sister and TOWIE star Jessica Wright and other family and friends, Michelle toasted Josh's special day.
Millwall footballer Josh, who featured on Saturday night's Strictly Come Dancing as he helped brother Mark with his balance and poise, turned 25 in style with a huge marquee party.
And Michelle dressed to kill in a black dress from her own Lipsy collection.
The lace panel maxi dress with leg splits showed off Michelle's fab body, while Jessica stunned in a simple black strappy number.
Very Hollywood glam!
Sharing pictures on social media, newly-single Jessica wrote: "Drinks with beautiful @michkeegan first thank you @krystal_iammakeup & @hannahwieteskax for our hair & make up."
After a night supping champers, Jess added: "Best party ever happy birthday @joshwright4444."
While all eyes were on birthday boy Josh, Strictly star Mark managed to grab the limelight for a quick dance with his mum Carol Wright.
Showing off his new moves, Mark looked dapper in a tuxedo.
While he has been keeping fit training for the BBC1 show, fiancée Michelle has been down the gym with sister-in-law Jess.
The pair have been doing power plate sessions together in a bid to carry on looking as hot as they do now!
Alongside a snap of them working out, Jess wrote: "Regram from today in the gym me & @michkeegan going for it 2nd day in a row training with @danib_gd."
Working hard, and playing hard - that's what we like to see girls!
