Mark, along with the rest of the Wright family, are currently in Alicante for Leah's forthcoming nuptials.
Leah's brother and Mark's cousin, Elliott, posted a video of the family enjoying themselves and it seems Mark was keen to show off his vocal talents!
Mark's dad, 'Big Mark', was certainly impressed, telling onlookers that his son was "good" on the mic! (Watch video below).
Yesterday, Elliott flew out to Alicante with girlfriend Chloe Sims, along with his cousin Jessica and her boyfriend Ricky Rayment.
Elliott, Chloe and her daughter Madison, joined the family for a meal at his restaurant Eduardo's Villamartin Plaza.
Captioning a photo posted to Instagram, he said: "Night before the wedding bells in #EduardosVillamartin with @chloe_simsstarship and my sister the bride to be!"
This morning (17 July), proud brother Elliott wrote a sweet message to his sister Leah, who will be tying the knot today.
Elliott said: "Just want to say good luck, I love you more then words can say.... You are going to look beautiful.... @leahwright_."
Aww good luck, Leah!
In last night's episode of TOWIE (16 July), Elliott told close friend James 'Arg' Argent that he was looking forward to escaping his recent drama with Ferne McCann for a few days, but confessed he was worried about giving a speech at the wedding.
Elliott said: "I can chill out, go to Spain, have the sun and be on the beach with my kids. I'm looking forward to the wedding though. I've got to do a speech Arg. I ain't that type of guy mate, do you know what I mean? Standing up in front of everyone and doing a speech!"
Arg, who has invited former flame Lydia Bright to Leah's wedding, then preceded with a pretty funny impersonation of Elliott: "I can imagine you going, 'Cheers! Yeah, for my sister, Leah'!"
The boys burst into laughter, with Arg assuring him: "It'll be alright mate."
TOWIE airs Sunday and Wednesday nights at 10pm on ITV2.
