The former TOWIE star joined sister Jessica at Disneyland Paris yesterday for a day hanging out with Mickey Mouse and the gang, while also supporting a very good cause.
Mark shared a selfie with Minnie with the joke caption: "When the wife's away.......... I had a selfie with Minnie today. Had a great time."
Mark and Jessica, along with young sister Natalya, were lending their support to British Airways and Disneyland Paris' third big event, flying deserving youngsters from London to Paris for a day at the magical theme park.
More than 40 young people from Carers Trust, Body and Soul, and Royal Docks Learning & Activity Centre took part in the fun day out, which was also supported by Stacey Solomon and Marvin and Rochelle Humes.
The group flew on a private plane to Paris from London City Airport where they enjoyed personal meet and greets with the Disney characters, lunch with the celebrities and, of course, free rein at the theme park, before heading home.
Mary Barry, British Airways' community investment manager, said: "Once again this great partnership between ourselves and Disneyland Paris will create lifetime memories for these very deserving youngsters. We are so grateful to all the celebrities who have given their time to come along and make the day even more special."
The big day out was part of British Airways' celebrations as the airline reaches £12 million raised for Flying Start, its global charity partnership with Comic Relief.
Meanwhile, former Coronation Street star Michelle is filming the second series of BBC One drama Our Girl, playing lead character Corporal Georgie Lane, taking over from EastEnders star Lacey Turner, who played Molly Dawes.
