Love Island viewers crowned Millie Court and Liam Reardon the 2021 winners on Monday night, but viewers have already predicted that they could split.
Some have suggested that once Millie gets a chance to watch the Casa Amor episodes back, she will break up with Liam.
When he was in the other villa, Liam flirted, kissed and shared a bed with Lillie Haynes.
But when he got back to the main villa he didn't take Lillie with him, choosing to recouple with Millie and keep what happened in Casa Amor a secret.
Despite Lillie telling Millie the truth, she decided to forgive him just days later and the duo were eventually crowned the winners.
She even decided to split the £50,000 money with Liam despite his betrayal.
Fans of the show had been calling for her to keep the money to herself as an act of revenge for what he did to her in Casa Amor.
And many viewers now think that once she gets the chance to watch it all back, Millie will end things with Liam.
One tweeted: "For everyone saying Millie and Liam are the strongest couple, you know she's going to watch the Casa Amor rerun when she's out the villa right?"
"I hope Millie spends her quarantine time wisely and watches Casa Amor," another posted.
A third wrote: "Iam gutted Millie & Liam won tbh, nothing against them I just feel like they weren't the same after #CasaAmor and I feel proper gutted for Millie because when she watches that she's gonna feel devo'd she graduated after what Liam did."
"When Millie watches back Casa Amor she's going to wish she didn't win," another agreed.
Another said: "Millie, I advise you to watch all of the Casa Amor episodes and decide wisely."
Just moments before they were crowned the winners, Liam had asked Millie to be his girlfriend.
During their exit interview, Love Island host Laura Whitmore asked them: "Well, you've already said the L-word, so boyfriend and girlfriend on the cards?
"You going to do a Chloe and Toby and get married? I don't think Toby knows that yet."
Millie replied: "I don't know, we definitely will be one day, won't we?"
In that moment, he asked her to be his girlfriend, to the surprise of both Millie and the live audience.
They beat Chloe Burrows and Toby Aromolaran, who were the runners up, to the crown.
Faye Winter and Teddy Soares came third, while Kaz Kamwi and Tyler Cruickshank came fourth.
