But the WAG wasn't about to let the small (or should that be rather big?) matter of a baby bump get in the way of wearing top to toe designer gear.
Col was seen on the phone outside the MEN Arena wearing a bold print dress with a white blazer and nude colour heels.
She is due to give birth to her second child any day now, and recently announced that she was expecting another boy.
Ahead of her night at Beyonce, Coleen was enjoying the sunshine with husband Wayne and three-year-old son Kai.
Tweeting a picture of the father and son in the park, she wrote: "Lovely day in the sun yesterday with @WayneRooney and Kai."
Coleen recently made headlines after getting into a spat with the Duchess Of Cornwall.
