Simone had left the Big Brother house in a shock double eviction, alongside Sue Evans, two weeks ago and had been reunited with her co-stars during Friday night's live final.
However, she later took to Twitter to reveal the drama that had taken place in the crowd, following an altercation she'd had with Andrew that led to security removing her from the scene.
My family are going to be so proud.'Andrew, meanwhile, had been in the Big Brother house until the very end, but was ineligible to win the show.
He had entered the Elstree compound as a Second Chance housemate and was given the challenge to out-stay his fellow latecomers on the show.
Fans, however, noticed that Simone had been absent from Big Brother's spin-off show Bit On The Side following the live final, with many taking the opportunity to criticise the glamour model for her actions.
They penned: 'Is it true Simone got removed from the #BBUKfinal because she spat at Andrew when she left the #bbuk house?
