POLICE are investigating controversial reality television star Lisa Oldfield, after she was accused of trolling the 13-year-old son of a co-star online.

The Real Housewives Of Sydney star reportedly attacked the teenage son of Victoria Rees last week, in a post she was forced to delete by Foxtel, who produce the show.

The teenager had asked Oldfield to leave his mum alone on the show, to which she reportedly replied with the suggestion that his mother was not supervising him because she drinks 30 cocktails a night.

She also reportedly told him to call his father because, “he loves you very much”.

The controversial 41-year-old wife of former politician David Oldfield defended her comments to the Daily Telegraph, saying the 13-year-old had attacked her first.

“He called me jealous and a loser, I think it is appalling that he would speak to an adult in that way,” she said.

“I don’t go around picking on children, I actually thought my response was quite measured and I signed off with a kiss.”

A NSW Police spokeswoman said the matter was reported on the morning of April 3.

No charges have been laid.

Foxtel confirmed they also spoke to both housewives over the incident, after ordering Oldfield to remove her comments.

“Foxtel and Matchbox have spoken to all of the Real Housewives about being responsible and respectful on ­social media,” a spokesman told the Daily Telegraph.

The boy’s request of Oldfield came just days after she publicly attacked his 52-year-old mother for calling her fans bogans during filming.

In an interview with the Daily Telegraph’s Confidential, an enraged Oldfield blasted Rees as, ‘a f***ing nobody”.

“She’s slagging off people that live in the West ... she’s a f***ing b***h,’ Oldfield raged to the publication.

“She’s a lonely old bag and she deserves to be because she’s a horrible person.

“She should be pitching frozen meals for one and incontinence pads.”

Oldfield has never been far from controversy since the show aired in February.

Shortly after its debut, she bizarrely uploaded a video of her four-year-old son Bert crying hysterically, before offering him, “a cigarette, a scotch, a joint, or a punch in the guts.”
