Last night, viewers watched as Dreamboy Rogan reunited with his former flame Jess Impiazzi, abruptly ended his fling with his co-star as a result.
Recalling the moment she found out Jess had arrived, Anita said: "It was really difficult for me, suddenly I was dropped and [Rogan] was with someone else... it made me feel a little bit worthless."
Prior to Jess' arrival, Anita and Rogan's romance had been heating up and the pair did hook up. But on meeting his ex, the fitness model decided to focus all his attentions back onto Jess instead.
In a new behind-the-scenes clip shared by MTV, Anita reveals she was left hurt by her co-star's actions.
She said: "To be dropped by someone... it's not nice. You start doubting yourself and thinking other girls are better than you, it's horrible. I did try and keep it to myself, until I saw them together and [Rogan] was happily flaunting it in my face.
"For a girl it's not nice to see the guy you like go with someone else," she added.
"I think the fact that I had actually slept with him made it more real to me that he didn't have feelings for me. It was a casual fling. Girls get more involved than guys do."
Meanwhile, Jess has insisted she didn't want to step on anyone's toes and did feel bad for the way her ex-beau had treated Anita.
"When I found out Rogan had dropped Anita and come to me, I did feel terrible," claimed Jess. "I know Anita told some of the other girls she had been pushed out, I didn't want to do that."
On finding out about Rogan and Anita's bedroom antics, the 24-year-old said she was hurt more by her ex-boyfriend lying to her.
She continued: "I was cross with him because he lied to me, I said have you kissed her and thought there would be no drama, but we all know it was a little bit more than that..."
Talk about drama!
