Rebecca, 21, made her arrival during Monday night’s episode as part of the Dirty Dancers challenge and instantly sent the pulses of Connor Durman and Callum Jones off the charts.
As Connor, 25, and Callum , 23, had the highest heart rates during the carer’s raunchy dance performance, she was later given the opportunity to go on a date with both of the guys.
However, viewers who tuned in were left somewhat distracted by a random “patch” that had appeared on Rebecca’s leg as she sat down to chat with the two blokes.
Following the discovery, fans flocked to social media to share their confusion about the white patch.
One viewer said: “I’ve just realised, none of the islanders smoke on camera? Like ever? Throughout the series?
“Noticed Rebecca wearing a patch. Is there like a rule idk about?? Why is it so deep?”
Other viewers wondered if the patch was in fact contraceptive.
A second viewer tweeted: “I’m just getting round to watching but is that a contraceptive patch on Rebecca’s thigh?”
While third went on add: “What the hell is Rebecca wearing lol contraception or nicotine patch?”
Meanwhile, other viewers were in disbelief when they discovered Rebecca’s age following her date scenes.
Speaking in The Beach Hut, Rebecca said: “I’ve come in here to find someone. I’ve not come in here to mess about.
“I’m ready to go in there and step on people’s toes.”
Speaking to the brunette beauty, Connor said: “You’re only 21? I thought you were older.” Before Rebecca replied: “Yeah, everyone says that.”
