Last night's Weekly Hot List episode saw the pair's bromance reach new romantic heights.
While they were hanging out with their partners, the boys kept in contact via text.
Kem told Chris: "Love you x"
Chris replied: "I love you so much baby".
Kem replied: "<3"
"Nap later me and you?" asked Chris, as Olivia and Amber remained oblivious to their text flirting.
Elsewhere in the episode, the pair were also seen spitting lyrics while showering naked together.
Fans have called on the pair to officially couple up - and win the show in Monday's final.
"In the final of #LoveIsland can we just vote for kem and chris to win together?😂" one asked this weekend.
Another agreed: "Chris and Kem should actually win #LoveIsIand though. They are a dream couple."
A third added: "Kem and Chris bromance is everything like can they just couple up and win the show? #LoveIsland"
On Friday night's show, the guys explained to Amber and Olivia their bond.
Kem said: “These things happen, we didn’t want to click but this is just fate.”
Chris added: “Sometimes you can’t help the click, the click comes and finds you.”
“I think we’re going to be best friends for the rest of my life,” Kem began.
“Forever and ever,” Chris finished.
The girls rolled their eyes as Olivia said to Amber: “Imagine coming on Love Island and meeting a boy who felt about you the way they feel about each other.”
“That is the dream,” Amber replied.
Love Island 2017 continues nightly on ITV2.
