Big Reunion star Michelle oozed sophistication in a slinky black and gold Pia Michi dress on Wednesday night (1 October).
Michelle even showed off the backless detail as she struck an over-the-shoulder pose outside the Langham Hotel to celebrate Lorraine's 30-year career in breakfast TV.
Any party is a good excuse to get pampered, and just hours before, the mum-of-two popped into popular celebrity salon Inanch London.
Updating fans on Twitter, Michelle shared a photo of herself with rollers in her hair.
She joked: "I'm sorry what?? I have something in my hair??? Lol #hairprep by @InanchLondon & @LMccrudden."
Michelle was later photographed leaving the salon and beamed as her dark hair extension draped down to her lower back.
The party was quite a glitzy one, with TV presenters Andrea McLean, Kate Garraway and Fiona Phillips in attendance, as well as pregnant Good Morning Britain presenter Charotte Hawkins.
Michelle tweeted last night: "Thank you so so much for inviting me to celebrate with you @reallorraine and the whole @ITVLorraine team. Here's to another #30years."
