Katie Price is reportedly being investigated by police over a revenge porn claim after she shared a sex tape of her ex Alex Reid to a live studio audience.

According to The Sun, the TV star was said to have been 'drunk and giggling' as she aired the clip while taking a break from filming Celebrity's Big Brother's Bit On The Side which showed the cage-fighter in drag and performing a lewd act with a sex toy.

This comes after the former glamour model, 39, admitted last year that she had 'disgusting' and 'disturbing' footage of Alex but vowed never to make it public because it would be 'so embarrassing him for him.'

The new claims against Katie comes a day after she addressed parliament about cruel bullies who take aim of her 15 year-old son, Harvey - who is blind and has a range of health problems.

Katie is said to have played the offensive clip - which saw Alex wearing a corset and fishnets - to 40 strangers as she took a break from filming the CBB after-show on January 9.

One witness revealed: 'She had asked us if we wanted to see it, and none of us replied.

'We all watched it, but we didn’t react. No one was laughing or cheering her on or anything like that. We didn’t want to encourage her,' it was continued.

Both Katie and Alex's representatives declined to comment when approached by MailOnline.

It remains unknown if the incident was reported by Alex - who was wed to Katie from February 2010 to March 2012 - or a guest at Big Brother’s Elstree ­Studios, in Borehamwood, Herts.

Gone back on her word? Last year, Katie admitted that she had 'disturbing' footage of Alex but vowed never to make it public because it would be 'so embarrassing him for him'

A police spokesperson told MailOnline: 'Officers are investigating an allegation of harassment through the disclosure of a private act, which is reported to have occurred at Elstree Film Studios in Borehamwood between 10.30pm and 11pm on Tuesday, January 9.

'Enquiries are on-going and it would be inappropriate to comment any further at this stage.'

In July of last year, Katie admitted that she would never show the 'disturbing footage' of Alex and expressed her desire that he would stop criticising her because she had far more incriminating things to show about him.

She told Heat magazine at the time: 'When I've split up with exes, they've gone on a rampage, slagging me off. The only way I get retaliation is I do books, but I don't slag them off, I tell the truth.

'Now, with Alex for example, the amount of stories he's done on me, but he forgets what videos and pictures I have of him. All my friends have seen them, but not once have I ever put them out.

'One, it would disturb everyone to the grave and number two, they're not flattering, they're disgusting. You look at them and you're disgusted.'

Katie ended her marriage to Alex in 2011, just 11-months after their wedding day.

In a lengthy statement issued via her publicist at the time, she conceded she married the athlete 'too quickly', but accused him of being 'fascinated' by his new celebrity status.

In her cutting statement, Price accused her estranged husband of 'changing' from the 'man I fell in love with' when they started dating in July 2009 - just eight weeks after she split from first husband Peter Andre.

But Katie claimed his 'desire to promote himself caused a change in the dynamic of our relationship and contributed to our alienation'.

She married Kieran Hayler in 16 January 2013. Katie was previously married to Peter Andre from 2005 - 2009.

The reports of the recent revenge porn investigation comes after Katie took to parliament to describe how sick trolls single Harvey out and hurl racist abuse at him on the internet - even creating videos of him.

She went to the police but they were left 'embarrassed' and unable to take cases any further because there was no criminal offence in place.

The mother-of-five is calling for a new criminal offence - which she has dubbed 'Harvey's Law' - to be created to make online trolling a specific crime.

Speaking about her son, Ms Price said: 'He is mocked for his colour, his size, I just think they think he is an easy target to pick on.

'But I'm his voice. I'm here and I'm going to protect him.'
