The former TOWIE star was joined by a very excited bunch of mates at Gatwick Airport ahead of a flight to Las Vegas, before he ties the knot with fiancé Michelle Keegan.
Sporting a very big smile, Mark clearly couldn't wait to jet off to the gambling mecca. Bet he won't look so fresh on the flight home!
The DJ was joined by cousin and TOWIE star Elliott Wright, who we already know was seriously excited about the Nevada trip.
Taking to Instagram yesterday, Elliott shared a photo of a Vegas pool party, along with the caption: "So the count down [has] started... In a few hours the journey begins... 38 of us ready to make my little cousin @wrighty_ stag... A few days to remember...! #VivaLasVegas."
We know what happens in Vegas stays in Vegas, but we'd love to see the antics Mark and best mate James 'Arg' Argent get up to over the next few days. Just imagine if the TOWIE cameras were following this lot!
Nothing says lads holiday like an army of guys in customised T-shirts, and thankfully this lot got the memo. Every stag member wore a T-shirt emblazoned with the message 'Vegas 6 May-12 May 2015: The Wright Way.' We see what they did there.
With a whopping 38 members of the stag do, it's certainly going to be an eventful trip. Good luck to everyone on the same plane!
This isn't the first of Mark's stag celebrations, as he also enjoyed a pre-stag night party in Essex, naturally.
Mark's stag holiday in Vegas comes after Michelle recently enjoyed her own hen do in Dubai.
Joined by a group of 30 pals from Manchester and Essex, the 27-year-old spent four days in the Middle East ahead of her big day. Coronation Street star Brooke Vincent shared a few snaps from the getaway, and it looks like the ultimate girls trip!
However, Michelle revealed she had a three-day hangover afterwards, ouch!
