It follows a saucy new challenge in last night's latest show.
It all started when Gabby got a text, explaining: “Girls, it’s time to find out who really gets your heart racing in tonight’s challenge Heart Strips a Beat.
"One by one, the boys will entertain you all with a sexy strip tease.
"The boy who gets your heart racing quickest will be declared the winner. #pulsesracing #getyourkitoff”
The girls were hooked up to heart rate monitors as the boys took to the stage in turn.
Gabby said in the Beach Hut: “Tonight’s performance for the lads - to say it took a lot of balls is an under estimation!”
But the task ended with awkwardness when the results were revealed at the end of the challenge, with Theo getting Gabby's heart racing more than her partner Marcel.
In a rather awkward chat after, Gabby brushed off the result but viewers weren't convinced.
One claimed: "Oh man Gabby digging herself a hole here... game player. Mask is starting to slip Gabs #LoveIsland "
A second accused: "Said it before but Gabby is not that into Marcel she has only stuck with him cus no other guy has fancied her. #loveisland"
"Marcel get rid of Gabby. She ain't into you and you can do much better #LoveIsland," posted a third to Twitter.
And finally, one concluded: "Gabby is not into Marcel FACT #loveisland"
Love Island 2017 continues nightly on ITV2.
