The Coronation Street actress wore a sexy low-cut black dress when she attended an 'American Diner' themed ball, hosted by co-star Simon Gregson and his wife Emma Gleave.
Samia, 30, admitted last May that she'd spent £4,000 on a breast enlargement - reportedly from an A to C cup - after her body changed following the birth of daughter Freya, now three.
At the time, she said: "Women's bodies change when they have children, and it was a personal thing for me.
"I wanted to feel womanly again. Just the thought of putting a bikini on on holiday was making me feel a little depressed before, so I made up my mind to do it."
Fellow Corrie stars Catherine Tyldesley also attended the ball on Saturday night (June 15) and got into the spirit of the theme in a polka dot swing dress.
While hosts Simon and Emma dressed as Grease's Danny and Sandy.
