Caitlyn Jenner was confronted by angry members of the trans community who protested outside a charity event on Thursday.

The demonstrators were angered that the 66-year-old former Olympian, who they dubbed 'a clueless rich white woman,' was being held up as a representative of their community.

The reality star had been speaking at a luncheon held by an LGBT charity in Chicago and attempted to engage with the protesters as she left, sparking a confrontation which was caught on camera.

Shouting slogans such as 'You are an insult to trans people, you are an insult to women,' protesters used a loud speaker to make their feelings known.

In a video of the altercation posted on Facebook by the protest group, Caitlyn can be seen being angrily berated, with demonstrators telling her 'you have no right to represent us.'

In the footage the I Am Cait star, 66, attempts to reason with them, before she is escorted away by her security guards.

Caitlyn had earlier given the keynote address to an audience of 1,000 at the Speaker Series luncheon for the Chicago House.

The charity provides social services for those affected by HIV/AIDS and other LGBT issues.

The protest group, calling itself 'I Ain't Cait', explained in a mission statement that Caitlyn's wealth made her unrepresentative of the average member of the trans community.

'Caitlyn Jenner... lives in a mansion and has a net worth of millions of dollars, while the average trans person has a 41 percent chance of experiencing homelessness and a nearly 50 percent chance of living off less than $10k per year,' they wrote on Facebook.

The group attacked Caitlyn for her past comments on those using social services such as Chicago House, quoting from her show.

The group called her: 'a clueless rich white woman who thinks disenfranchised trans women of color should just pluck themselves up off the street and stop being so lazy.'

And they added: 'Caitlyn Jenner doesn't represent trans people!'

The protester who was seen confronting Caitlyn in the video, later said in a public Facebook post that Caitlyn gave her a 'look of disgust'.

And she wrote: 'I support her as trans, but I won't support her as an act of bravery for transitioning in the public's eye, while millions are homeless for identifying, dead, or dying because they have to do damn near anything just to find a place to sleep at night.

'Those are the folks that I pray respect and support my direct advocacy for humanity and dignity for all. Everyone can be productive if given a chance and left alone to figure it out.'

Since Caitlyn announced she was transitioning from male to female back in April during an interview with Diane Sawyer, the former Bruce Jenner has been held up as a poster girl for trans women.

She received the Arthur Ashe Courage Award during the 2015 ESPY Awards in July 2015, and was named one of Glamour's Women Of The Year in October, with the magazine calling her a Trans Champion.

In November, Jenner was listed as one of the nine runners-up for The Advocate's Person of the Year.

A production source told Entertainment Tonight that Thursday's encounter was caught on camera for the second season of Caitlyn's reality show.

Caitlyn's castmates, Candis Cayne, Jenny Boylan and Kate Bornstein, were all in attendance, and Caitlyn sat next to trans MMA fighter Fallon Fox at the event.

The source insisted to ET that the encounter was not staged.

'We didn’t know Caitlyn was going to talk back to the protesters,' the source continued. 'None of it was staged.'
