Thankfully, the Brit will have someone to confide in with his close friends Timm Hanly and Jamie Doran joining the cast.
Brittany Hockley from Nick Cummins' disastrous season of The Bachelor is also heading to paradise with Bachelor stars Helena Sauzier, Mary Viturino, Jessica Brody, Brittney Weldon and Cassandra Mamone in tow.
Oh, and Jarrod Woodgate, who found love with Keira Maguire on BIP, will be returning for a second time.
Ok, now that's out of the way, let's get to the teaser trailer.
The clip begins with Ciarran walking onto the set butt naked with nothing but grapes covering his, ahem, you know what! Of course, Abbie nearly has a heart attack and later tells the camera that she hopes to leave hand in hand with the tatted-up hunk.
"I came here for Ciarran. He's hot and he's such a naughty boy," Abbie says. "He's mine. I am going to get him."
Unfortunately, Jessica is standing in her way.
"We had the most perfect kiss, in the most perfect setting," she says of her date with Ciarran.
Clearly, Abbie's devastated she didn't impress Ciarran as much as she'd like, saying during an explosive dinner party that "there's so much Ciarran has lied about".
"There's a lot of things that people don't know. He has just played everybody. If you want me to spill the beans, I will spill the beans and you're going to look like a piece of sh*t," one of the female contestants says in a voiceover.
Leaving Brazilian brunette Mary Viturino and jewellery designer Cassandra Mamone visible shocked, Ciarran storms away from the table, saying: "F*** off! I'm f***ing going!"
