Fans of the show will remember Olivia and Scotty got together on their first night in the villa, however, she quickly nipped any romance in the bud after her ex-boyfriend of three years arrived.
Now, though, Olivia is hoping to bag Scott all to herself again and it's fair to say Nancy is NOT happy...
Throughout the series, Nancy and Scott have had us hooked with their on/off romance and the love triangle they have got going on with Lacey Fuller.
Scott has been going back and forth between the girls, but his bed-hopping antics finally catch up with him and he is confronted by both Nancy and Lacey in tonight's episode.
The girls basically tell him he can't have his cake and eat it and Scott finally admits to both Lacey and Nancy, it's Nancy he wants. He has to prove it, though, and Nancy is keen to hear what the Geordie charmer got up to when he was sent on a yoga date with Olivia.
During the date, Olivia admits: "I really regret stepping away from Scotty T when James came in…I did really like Scott."
Scott, meanwhile, does his best to avoid locking lips with Olivia, but it all kicks off between her and Nancy.
The girls get together to discuss Olivia's date and Nancy makes the decision to break things off with Scott - convinced he is not going to change for her. She then realises that Olivia is hoping to get back in there with Scott and brands her a "sly sl*g" before, of course, the whole "girl code" debate is brought up.
Drama, drama, drama. Is there ever a non-eventful day in that villa?
Ex On The Beach continues tonight Tuesday 1 March at 10pm on MTV.
