Lizzie Cundy was left red-faced during her Talk TV show with Ash Gould on Sunday after she fell to the ground and under the desk
The socialite, 54, could be seen standing up while Ash explained to viewers they were adjusting the height of her chair.
Co-host Chuck Thomas then appeared on screen to the side of Lizzie and whipped her black office seat out from behind her.
Unaware the seating had been wheeled away, she went to sit down and plummeted to the ground.
Her leg could be seen flying in the air as she hit the floor with a thud, before the WAG burst into laughter.
Lizzie exclaimed: 'I thought you were there! I can't believe you did that to me Chuck!'
Chuck hit back: 'I was lifting your chair up, Lizzie!'
It comes after Lizzie revealed she'd bagged a Hollywood movie role as a 'feisty' Burlesque club owner.
The psychological thriller will see her work alongside Game Of Thrones and Westworld director Neil Marshall, 52.
With filming on Compulsion set to begin next month in Malta, Oceans 8 star Charlotte Kirk, 30, is taking the lead role while directing too, having co-written the film alongside her fiancé Neil.
Lizzie exclusively told MailOnline: 'I've been offered this new role and I'm absolutely thrilled! I'm going back to my acting roots, which is my first love since a child.
'I did WAG! The Musical in the West End, which I adored, and this new movie part is just made for me so I thought why not?
'Life is for living and I want to do everything in life and live life to the full. It's an exciting, feisty role, very much like my real self.'
