The 27-year-old mum-of-two chose a figure-hugging frock with a sheer top for her appearance at the benefit evening, held at Manchester United's Old Trafford stadium. She completed her vampy look with smoky eye make-up and pale lips.
Coleen was also sporting a glowing tan, thanks to a recent family holiday in Barbados with her sons Kai, four, and nine-month-old Klay.
Coleen looked stunning alongside her husband Wayne
It was while she was away that husband Wayne, 28, secured a new deal with Manchester United worth £85.5million - around £300k a week, making him the highest paid player in the Premier League.
The couple seemed in high spirits as they arrived at the football club for the United for Colitis charity event. The evening, which featured a mix of fundraising and entertainment, was organised to raise money for Crohn's and Colitis UK charities.
Footballers Rio Ferdinand and Robin Van Persie were accompanied by their wives to the event
Man United's Darren Fletcher, who was diagnosed with ulcerative colitis in 2011, co-hosted the event and was among the speakers on the night, alongside ex England rugby star Lewis Moody, who suffers from the same disease.
Other sports stars attending the benefit included Rio Ferdinand, who brought along his wife Rebecca Ellison, and Robin Van Persie, who stepped out with wife Bouchra.
