The former footballer, who is currently filming the new series of TV show A League Of Their Own, shared a snap on his Instagram account from Tuesday night’s bash.
At the event, a smartly-dressed Jamie posed for a picture with British rapper Santan Dave, 21, and shared the image with his 1.1 million followers.
Taking to his Instagram Stories yesterday, he captioned the image: “I think I got the dress code wrong”.
On Tuesday night, Jamie attended an after party for the second worldwide screening of The Broken Butterfly at The Arts Club in London.
He was snapped with rapper Professor Green, 35, at the event, who was also sporting a less formal look.
The London-born performer teamed a black T-shirt with matching trousers and trainers in the same colour for his night out.
Professor Green, real name Stephen Manderson, placed his arm around the sports star for the cosy snap.
Earlier today, Jamie’s ex wife Louise Redknapp, 45, was snapped getting hot and sweaty at a charity KOBOX class.
The singer, who shares two sons Charlie, 15, and Beau, 10, with the Sky Sports pundit following their 19 year marriage, showed off her gym-honed figure in a crop top and leggings after a boxing-based full-body workout.
Pussycat Doll Ashley Roberts, 38, joined the singer for the class, which raised much-needed funds for Rainbow Railroad – a charity which helps members of the LGBTQ community escape violence and persecution in their own country.
