The fashion designer wife, 28, of Wayne Rooney wore a fitted monchrome dress as she leant her support to the Christie Hospital and Key 103 Cash for Kids charity initiative.
Cash for Kids raises money for disadvantaged and disabled children and young people in Greater Manchester under the age of 18.
Coleen attended the charity luncheon shortly after returning home to the UK from Paris, where she enjoyed a trip with her best girlfriends to watch Beyoncé and Jay Z performing their final 'On The Run Tour' date.
Lucky for some!
Mum-of-two Coleen posted to Facebook after her visit: "Great weekend in Paris with the girls. Beyoncé and Jay Z concert was brilliant!"
As well as taking in the concert, the star also found time to visit some of Paris' biggest tourist sights, including the Eiffel Tower and the Pont Des Arts bridge, where she left a lovelock padlock bearing her and Wayne's names.
And then earlier this week, the Littlewoods designer was also pictured enjoying a night out with Wayne and his Manchester United teammates at Neighbourhood Bar & Restaurant in Manchester City Centre.
