The 'Geordie Shore' star - who recently came out as bisexual - is "so happy" that her co-star is making an "effort" to spend quality time with her, even though he won't make an official commitment.

Asked if they are seeing each other, she said: "I think so. Normally Aaron makes up every excuse in the book to avoid me. He hates doing anything with us. I can't believe he's actually making an effort. I'm so happy.

"I've always wanted him and until I fully have him that probably won't go away.

"For some reason he won't ask, 'Do you want to be my girlfriend?' I think he's scared to put a name on it in case he f**ks up."

Despite her feelings for Aaron, Marnie will walk away from any relationship with him if he doesn't make a commitment to her before the next series of 'Geordie Shore' starts filming.

She told Star magazine: "There are rumours we're going abroad again. Girls on holiday are so horny so I think the boys will go a bit crazy.

"If I'm not Aaron's girlfriend by the time we go in, I'm going to leave it and be single with the girls. I can't do a full series of plodding on."

And if Aaron does get with another girl, Marnie will be out for "revenge".

She said: "I would get revenge and make him jealous.

"I'm not one of those girls who would sit and cry over it. If things don't work with Aaron, I'd get into a relationship with a girl. I don't want to waste any more time on boys. Even though it is still a bit uncomfortable for me, I'd go for it."
