The pair remain an official couple (at the time being) having been through numerous rows and break ups over the past two months.
In this evening's episode the couples were woken up by the sound of babies crying and were tasked to play Mum and Dad, looking after baby simulators which required everything from feeding to nappy changing.
Chris immediately took to his role as a new father like a duck to water: “I think this morning he has already brought out an emotional side in me."
However Olivia described it as a "nightmare", before naming their son Cash after her "favourite thing.”
Later in the garden, Chris was overwhelmed by the emotions of becoming a new father. He told Olivia he had a tear in his eye because he cares so much about their baby.
But Olivia concluded: “I have been a mum for a whole four hours and I’m done with it.”
Viewers are now backing Chris to (somehow) win without Olivia in next Monday's final.
"DILEMMA. I really really want Chris to win. But not Olivia. How do we make this happen?" one viewer posted on Twitter tonight.
Another agreed: "Petition for Chris to win love island without Olivia #LoveIsland"
A third added: "Want Chris to win so bad. Want Olivia to not win so bad. #dilemma #LoveIsland"
Love Island 2017 continues nightly on ITV2.
