A TV source said: “Mark has already had an incredibly busy year presenting on Extra.

“Now he’s getting ready to jet off again to front another show which is an amazing opportunity – but it means more time out of the country and being apart from Michelle.

“He’s really excited to get stuck in with the show though and looking forward to lending his professional dating expertise.”
