Tulisa Contostavlos joined I’m A Celebrity at the weekend alongside a lineup of various other famous faces and tonight (November 20), she opened up about her arrest back in 2013.

The N-Dubz singer was arrested on suspicion of supplying class-A drugs.

Tulisa’s charges were later dropped after prosecution witness “fake sheikh” journalist Mazher Mahmood was found guilty of tampering with evidence, during her 2014 trial.

Speaking to Oti Mabuse in the jungle, Tulisa said: “2013 was the year I was set up by a British newspaper, for concern in the selling of class A drugs.”

She explained: “The guy’s name was Mahmood and basically, I was approached by a big movie company and they sent me a tweet or a DM from their official account to audition me for a movie role…"

Tulisa added that she had "dabbled in acting" so the opportunity for the role was a big deal for her.

Contostavlos said the role was offering £3.5 million and she was flown out for meetings with producers in Las Vegas with “first-class flights, limousines (and) five-star hotels”.

“I found out it was a lie,” she told former Strictly Come Dancing star Mabuse.

“So I was told, as I wasn’t an actress, I was less likely to get the role and the only reason I would get it is if I was the girl in the role, and the girl in the role was this bad girl from London who was constantly up to naughtiness, rolling with gangs, up to all kinds of naughty stuff.”

Contostavlos said “They had me dangling on the end of a string”, claiming every time she met with the team they’d tell her “We need some drugs”.

“After months and months, eventually they got a number and it was of someone that wasn’t even a drug dealer, it was an aspiring movie producer and I wanted to make a hook up as well for that person, but I didn’t know anyone that could do that,” she said.

“The long story short is they ended up ordering £800 worth of cocaine from the number that I had given them.

“Then before I knew it, I was being arrested in the concern of the selling of Class A drugs and I was facing four years in prison.”

Contostavlos revealed she lost “all my endorsements” over the incident.

“My life fell apart,” she said.

The 36-year-old continued: “When it came to the trial, I’d had a conversation with one of their drivers, I was being recorded but I didn’t know, I was saying how anti-drugs I am, so they were very aware of my feelings towards drugs.”

Contostavlos said the driver initially gave a statement confirming she was anti-drugs, however, she claimed that as the trial loomed the journalist forced him to change his statement.

In 2016, Mr Mahmood was jailed for 15 months for tampering with evidence in the collapsed drugs trial of pop star Contostavlos following a two-week trial at the Old Bailey.
