Russell Brand is having the "best sex ever" with new girlfriend Jemima Khan.
A source revealed that the comedian and his socialite girlfriend – who have been dating since June – have amazing chemistry between the sheets, to her mother's dismay.
The insider told The Sun: "She's never met anyone remotely like him and he makes her feel incredible. She's also never met anyone who is so adventurous in bed. She can't get enough of him. She just says he ticks every box.
"Her mother is trying not to let her panic show because she doesn't want to push her further into his arms. She's being as pleasant as possible, but any mum would be terrified at the thought of Russell Brand squiring their precious daughter.
"Her friends are worried, it's to do with what he says about people he knows and that he's slept with so many people."
The revelation comes after the pair were reportedly told off for getting intimate on the couch at a party thrown by PR boss Matthew Freud at his London home.
The Daily Mirror quoted an insider as saying: "Russ and Jemima were curled up together, and what started out as flirting quickly got embarrassingly passionate.
"Pretty soon, they were wrapped up in each other and wriggling around like teenagers. Some people thought they needed to get a room. In the end, Matthew went over and had a quiet word."
