Coleen, 28, wore all-black to the event, which was held at Old Trafford, and smiled alongside her husband Wayne, also 28, as they posed for pictures together.
The mum-of-two teamed her Saint Laurent LBD with a pair of skyscraper heels and showed off her slim waist with the help of the frock's cute matching black belt.
Coleen topped off her look with a half-up and half-down hairstyle and carried a small black clutch. Wayne, meanwhile, looked dapper in a suit and black tie.
It is thought Coleen picked up her dress from her favourite store in Liverpool, Cricket, and the shop has been quick to gush on Twitter about how stunning she looked.
"Swit swoooo...@ColeenRoo masters summer black in Saint Laurent. Utterly gorrrrrrgeous on you!!!" Cricket tweeted.
It was a rather busy day for the couple yesterday (8 May), as Coleen and Wayne had also spent the afternoon at the races in Chester.
