It's not everyday you stop to get on a tube and notice your wife's face splashed across the wall in front of you, but exactly that happened to Mark and he took full advantage of it.
Michelle told BANG Showbiz that Mark took a selfie in front of an ad for Michelle's Lipsy clothing line, and joked to his wife: "Oh my god, everywhere I look you're there."
Kinda funny, right?
Michelle made the revelation in an interview with BANG Showbiz about how supportive Mark is towards her work.
She said: "He [was] on the underground and there's a big poster of me - I didn't know that by the way - and Mark sent a picture saying, 'Oh my god. Everywhere I look you're there."
"He was at the [tube] window and took a selfie," Michelle explained. "I'm through the window in the picture. He's really supportive like that."
Mark and Michelle married in May last year, nearly two years after getting engaged.
They had initially met in Dubai in 2012, before Mark popped the question in September 2013 when the couple returned there on holiday. Michelle actually opened up on Mark's proposal during an appearance on The Jonathan Ross Show recently and gushed how it had all been "very romantic."
She told Jonathan: "It was all planned, it was when we were in Dubai and it was four days into the holiday, so I had no idea." He did it on the beach and there was a table set out with a waiter and candles... When we first started speaking, I did say that one day I'd like to get proposed [to and be] in a white dress and all that - the fairy tale.
"[Mark] told me a story that on the beach there was going to be a white party so I got a white dress and I didn't think anything of it, but he had it all planned out so I wore the white dress, I was on the beach... it was very romantic."
Since tying the knot, Mark and Michelle have constantly been quizzed about starting a family together, but while Michelle has admitted she is "always broody", the 29-year-old confessed she and Mark aren't planning on having a baby just yet.
Speaking on the red carpet at the Pride of Britain Awards in October, Michelle said: "I love children, I've always said that I'm broody... but we're not planning anything of yet."
Instead, she and Mark are currently focusing on their work commitments. Fans have seen Michelle star in BBC drama Our Girl and the actress has confirmed that she'll be returning to the show for a third series.
Michelle is also set to star in upcoming ITV drama Tina and Bobby.
Mark, meanwhile, is a DJ for Heart FM and is preparing to start filming for another series of Take Me Out: The Gossip.
