Gemma, 33, was reportedly driving the hired black sports car around the streets of Marbella in Spain when she accidentally scraped the paintwork.
According to a source, the star didn't even realise her mistake because the noise of the roaring engine masked the sound. Oh dear!
"Gemma was driving the car really confidently going round tight corners but ended up badly scratching it without even realising," the source told The Sun.
"She claimed the engine was so noisy that she couldn't hear anything."
Last night, TOWIE fans saw Gemma pull up outside a cafe in the car, declaring to Bobby Norris: "GC's in Marbella!"
Gemma then told Bob that the car was better than any man she has ever been with.
It was an emotional episode for poor Bobby, as boyfriend Harry Derbidge told him he'd slept with his ex during a holiday in Tenerife earlier this year.
Being friends with both guys, Gemma found herself caught in the middle but didn't hold back on telling Harry that he was out of order.
Following the show, Gemma's co-star Mario Falcone, who didn't go to Marbs, made reference to her while tweeting about the steamy scenes between Chloe Sims and Elliott Wright.
Mario joked: "If I had been in Marbs... It wouldn't have been Elliott and Chloe frolicking on the beach.. Would have been me and @missgemcollins ha x."
