First returning Love Island star Calum Best entered the villa and whisked the boys off to Magaluf, and now, former TOWIE star Mark will be joining the gang and getting them in the party mood.
Sadly he won't be staying in the villa (clearly he doesn't need to now he's happily married to wife Michelle Keegan), but he will be DJ'ing for Lauren's birthday bash.
Ahead of heading into the villa, Mark has said: "I'm really excited to be going in to DJ at Lauren's party, I've been addicted to Love Island and I'll be making sure I get all the gossip whilst I'm in there."
Oh, we've no doubt he will.
Used to grilling potential couples on who's dating who thanks to his stint as presenter on Take Me Out: The Gossip, Mark will have no problem getting the low down on all the in-villa romances.
We. Can't. Wait.
According to The Sun, show bosses were just as eager to get him on the show as we are to watch, reportedly offering the reality star a cash offer he couldn't refuse.
A source told the paper: "ITV have been desperate to get him out there for ages as they're convinced he'll boost ratings. They ended up offering him a huge wedge of cash and he agreed to go out and take part."
Viewers will be able to see Mark's fun-filled evening with the Love Island gang on Tuesday night.
Meanwhile, our Islanders have been enjoying their last few days in the villa as they prepare for the Love Island final on Wednesday night (15 June).
Following Jordan Ring and Zoe Basia Brown's exit last week, the remaining couples left and battling it out for the title are reunited couple Max Morley and Jess Hayes, Jonathan Clark and Hannah Elizabeth, Luis Morrison and Cally Jane Beech and Josh Ritchie and Lauren.
Following their departure, Reveal caught up with Jordan and Zoe who told us they're backing Max and Jess to win.
While many watching the show have questioned whether Max's feelings towards Jess are genuine - he failed a lie detector test when asked if he was happy to be coupled with her again - Zoe has insisted he "really does care" about her.
"I think he genuinely does like her," she told us. "He wouldn't have reacted in such a way if he didn't like her and didn't want her to think badly of him. If he didn't care, he would have just brushed it off. The fact he had such a big reaction shows how much he likes her."
