The ex-TOWIE star posted a heartfelt collage of photos to Instagram on Friday (3 June) for Michelle's big day, alongside the message: "Happy birthday to my best friend, partner in crime and love of my life. My wife @michkeegan."
Mark and Michelle, who turns 29 today, celebrated their one-year wedding anniversary in May, with Michelle marking the day with a throwback to their ceremony, and Mark having the date of the wedding inscribed in his football boots. So David Beckham!
The couple married in a fairytale ceremony in Bury St Edmonds on 24 May 2015, and spent their anniversary on a romantic break. Mark told fans: "The most perfect time in the most perfect place with the most perfect person...."
Michelle's been very busy lately filming the new series of BBC army drama Our Girl, having taken over the lead role from EastEnders' Lacey Turner.
Mark, 29, meanwhile, has been preparing for the big Soccer Aid 2016 match, broadcasting live from Old Trafford on Sunday, 5 June. He's playing for Team England alongside the likes of One Direction's Louis Tomlinson and Olly Murs.
