The student, played by Valentina Novakovic, makes a big mistake in a forthcoming storyline when she sends raunchy photos to Ivan in a bid to prove how mature she is, according to the Daily Star Sunday.
It is thought that Ivan quickly betrays Natasha by sharing the pictures with his friends, causing a scandal at the school when the news spreads and her classmates find out.
"Tash doesn't think of the consequences when she takes a series of very naughty pictures of herself to send to Ivan," a source told the newspaper. "He's more than ten years older than her and she's desperate to keep him interested."
Natasha's father Michael (Sandy Winton) is expected to discover the situation when he overhears gossip about his daughter at the school.
The insider added: "Michael is disgusted when he hears the lads in school talking about his daughter. He jumps to the conclusion that Ivan put Tash up to it, so he's even more gutted when he discovers it was all Tash."
Neighbours fans have already seen Tash left heartbroken after her boyfriend Andrew (Jordan Smith) fell in love with Summer Hoyland (Jordy Lucas).
Her latest storyline will soon hit screens in Australia and air on Channel 5 in the UK later in the summer.
