In tonight's episode of the show, Kayleigh Morris is the FIRST ex to arrive and she is shortly followed by Jem's ex-beau David - who she confesses she is still in love with.
Heading down to the beach with Olivia Walsh and Kayleigh, Jem admits she is 'terrified' at the thought of David turning up to greet them and explains that he previously broke her heart.
She reveals that he 'once brought a girl back to his apartment, while she was still in his bed' and the thought of seeing him again has her tearing up.
Jem reveals she is 'dreading' the thought of potentially being reunited with him again, so you can imagine her face when her fears come true and Hawley emerges out of the sea.
He, meanwhile, seems to think revenge is on the cards and tells Jem: "You make a mug of me, I hope you're ready for me to make a mug of you."
This cannot end well, right?
Jemma doesn't seem to think so and breaking down in front of the camera, she claims: "I can't deal with it..."
Ex On The Beach returns Tuesday 16 August at 10pm on MTV.
