Rebel Wilson blames "obsessed" schoolmate for selling her out to Woman's Day

Actress Rebel Wilson has told the court an "obsessed" and "jealous" former schoolmate sold her out to 'Woman's Day' magazine for a "quick buck."

The 37-year-old actress is suing Australia's 'Woman's Day' publisher, Bauer Media, for damaging her career and painting her as a serial liar.

The magazine had run stories in 2015 about the 'Pitch Perfect' star lying about her real name, age and childhood, and accused her of telling "pork pies".

Emails between the journalist and the source saw the source attempting to negotiate fees in return for the information.

While Rebel Wilson's real name and age had been publicly revealed in the story, the actress argues the articles were deliberately timed to be published at the height of her career as 'Pitch Perfect 2' was being released.

She claims that she went from being Hollywood "hot property" to being sacked from her roles on 'Kung Fu Panda 3' and 'Trolls'.

As her movie offers dried up, she became so stressed over the two years that she developed sores, eczema, a urinary tract infection, and had to take sleeping pills. A number of scenes in her movie 'How To Be Single' were also deleted due to a sore breaking out between her nose and lip.

"Unfortunately in the rest of 2015 and 2016 I didn't do any lead roles or co-lead roles in movies or television," she told the court.

"They took those two years away from me doing what I love, which is entertaining people and making people laugh."

Rebel Wilson will continue to give evidence in the Melbourne court as the defamation case progresses.
