Paparazzi hanging out at the famous eatery got plenty pictures of the incident.
Right after the incident the 25-year-old reality star tweeted: “My dress has ripped up the back like where the split goes whole bums out?#fail?/ Haha Gemma the porn star is looking very conservative tonight. Widdecombe would be proud @LadyGemmaMassey.”
At least she was wearing undies!!!
