The 28-year-old and 35 of his closest friends flew to Sin City this week for his third pre-wedding celebration before he and Michelle Keegan, 27, tie the knot – and he's already blown a reported £35,000!
According to the Mirror, on their first night Wrighty and his pals spent £15,000 on vodka, champagne and beers at the Light Club.
Then on Thursday night they went to trendy nightspot Tao where the minimum spend for a group of their size is thought to be £20,000.
Joining Mark in Vegas is brother Josh, cousin Elliott and best friend James Argent – but he still can't keep his mind off of his wife-to-be.
Taking to Twitter this morning, Mark wrote: "Being out in Vegas is one thing but to keep me buzzing and smiling is knowing that in 2 weeks Im marrying the girl of my DREAMS. In and out [sic]."
And big Mark Wright has been keeping his future daughter-in-law updated. Michelle told the Mirror: "His dad and his mates have been sending me pictures!
"The one I got this morning is of him holding a picture of my face with a sign behind it saying Mr Keegan, which is hilarious!"
Earlier this year it was reported that the showbiz wedding of the year will take place at Hengrave Hall in Bury St Edmunds.
