Liberty X star Michelle was visiting ITV studios in London with her one-year-old when they bumped into the Disney character in the corridor.
Squealing with joy, Faith seemed almost overcome as she spied the giant mouse waving and strolling towards her.
Michelle was quick to take some snaps before arranging them into a cute collage and uploading them to Twitter.
Alongside the pictures, she commented: "The biggest squeal I've ever heard from Faith .. Ever! At @ITVLorraine." Bless!
Michelle is currently hosting Lorraine's Miami Beach Diet so has been heading to ITV a lot for filming. We bet she was glad to have little Faith with her on this occasion!
