Pixie Lott was reportedly left red-faced after getting thrown out of a concert that she'd opened for Rihanna.
The 19-year-old singer told Sugar magazine of her "embarrassment" after a security guard asked why she didn't have a ticket.
She said: "I'd just finished my set at the O2 Arena in London and my mum, dad and best friend were in a box and told me to come and join them. I'd just sat down when one of the staff said 'You don't have a ticket. Get out'."
The Boys And Girls singer added: "It was so embarrassing being escorted to the bar."
The full interview appears in the September issue of Sugar magazine, out now.
