Talking to Hello! about 24-year-old Frankie and fiancee Wayne Bridge's new arrival, Mollie allegedly said, "We're all very excited and can't wait to meet him." Uh oh!
You'd have thought she'd have realised her error at this point and quickly shut her mouth, but oh no. "It will be nice to have a little boy around," she continued. *Palm to face*.
The singer, who made her DJ debut at the We Love Pop night in East London on Saturday, eventually changed the subject and gushed over Una Healy and Rochelle Humes' baby girls, Aoife and Alaia-Mai.
"I have the best of both worlds", Mollie said. "I can cuddle them and spoil them then hand them back for the nappy changes and crying bit."
