A PRIMARY school teacher who used her purple muscle car to pick up a 13-year-old pupil for sex is heading to jail.

Christina Albini, 43, seduced her former student with nude selfies sent to a secret phone she bought him, a court heard.

And raunchy naked photos taken after a yoga class led to her downfall when they were found by his horrified mum.

The boy told investigators Albini would pick him up around the corner from his house in her Dodge Challenger.

The blonde promised to "be quick and have him back before his mother gets home", prosecutor Eric Costaris said.

At first the teen saw Albini as a "mother figure" when she befriended him in July 2015.

But soon they professed their love for each other and swapped sexually explicit messages.

Their first intimate encounter was said to have involved oral sex at her home in South Windsor, Ontario, Canada, in February 2016.

She was arrested five months later in July after his stunned mum found his phone and sexually explicit messages sent through WhatsApp and Kik.

Albini, who taught at Christ the King Catholic Elementary School, mentioned going to yoga in one - and sent naked snaps of herself from the studio.

Cops also found receipts for presents which Albini bought for the youngster, including the phone, an Xbox, bracelet and clothes.

Albini is facing at least a year in jail after pleading guilty to sexual interference.

Her lawyer, Patrick Ducharm said: "There's a minimum mandatory one year in prison and it goes up from there."

Other charges, including sexual assault, luring, possessing and accessing child porn and making sexually explicit material available to a child under 16 are expected to be withdrawn when she is sentenced next month.

Justice Micheline Rawlins ordered a background report on Albini before the June 28 hearing.

Last week it was reported that a nursery teacher was accused of bedding four pupils.

Heather Robertson, 28, reportedly had a threesome with a pair of them after inviting them to her home.
