Marv and the rest of JLS arrived back at Heathrow earlier today after spending a week partying in Las Vegas and Miami.
And judging by the looks on their faces they've got a serious case of the holiday blues no doubt combined with a few sore heads too.
Marvin's bandmates - Oritsé, Aston and JB - had spent months planning his stag do with military precision - even getting a former member of MI5 to help out with the planning.
At the time, he told The Sun: "I have met up with an ex-MI5 guy who is helping us plan Marvin's stag do. We are taking this thing deadly seriously and will be rehearsing it. It is a covert MI5 operation. This guy has told us he will help us get it done in the most discreet way so Marvin will have no idea what will hit him."
One person who will be pleased to see him back in one piece is his fiancéE Rochelle Wiseman of The Saturdays. She might want a few questions answered too after the stag party were seen partying with bikini clad girls on a yacht in Miami.
Let's hope he went shopping before he left.
