With her own hen do party done and dusted, the former Coronation Street star was free to join the likes of Ant & Dec, Emma Willis and Rochelle Humes at the star-studded ceremony in London.
As always, Michelle looked gorgeous on the red carpet, opting for a mint green gown that set off her Dubai tan.
Michelle, 27, is just back from her bachelorette celebrations in Dubai, where she partied up such a storm that she was left with a three-day hangover. Ouch!
She took 30 girls on her hen do including sister-in-law to-be Jessica Wright and former Corrie co-star Brooke Vincent.
Meanwhile, over in Sin City, ex-TOWIE star Mark is doing his own celebrations alongside pals including James 'Arg' Argent and his cousin Elliott Wright.
While Michelle was gracing the red carpet in London, Mark was enjoying the atmosphere at Encore Beach Club, where he was pictured looking uber tanned and in good spirits on day five of partying.
It's expected Mark and Michelle will marry in the UK later this month.
