Georgia Steel is left "fuming" at new girl Megan Barton Hanson in Love Island 2018 on Monday night.
Sunday night's show saw Megan join the villa alongside two new boys.
After making their initial entrance, Monday night will see the trio cause a stir.
They receive a text which reads: "Today you will each date three of your fellow Islanders. You must now ask out your first choice."
Megan makes her move on Niall Aslam, leaving his current partner Georgia angry.
"I'm fuming!" she reacts in the Beach Hut. "I’m fuming. Actually fuming. No one takes my man away, no. I’ve never had competition before and I don’t like it.”
Meanwhile, Megan tells Niall, “There were other boys I could pick but I wanted to pick you because I found you attractive.”
New girl Megan is a 24-year-old Model from Essex.
Speaking before entering the villa, Megan said she was going to offer something new: "I think the first obvious thing is my look. The other girls are all very toned and I’m quite curvy. I’ve got big boobs and a big bum. I’m very real. I’m more chilled than the other girls. In that way I’m more like a guy, very laid back."
Asked what she wanted in a man, Megan added: "Dark and tanned looks wise but I’m definitely more about personality. Some of my friends are like ‘what are you playing at?’ with the people I go for. I love it when you can chat endlessly with someone.
"I like Niall and Eyal. Niall is perfection – I have a thing for mouths and he has such a good mouth. Normally I go for older guys but both of them are so attractive. I’m quite spiritual and I like yoga and I think Eyal has more to him that I want to discover."
Meanwhile, new guy Josh Denzel picks Laura Anderson while Charlie Frederick chooses to date Samira.
Love Island 2018 airs nightly at 9PM on ITV2.
