In 2008’s Forgetting Sarah Marshall, Kristen Bell and Russell Brand were thrown into raunchy sex scenes - but Bell made sure of no funny business off-screen

Kristen Bell threatened to “lop Russell Brand’s nuts off” if he tried anything with her on the set of Forgetting Sarah Marshall.

The pair were brought together for the 2008 Hollywood rom-com - also starring Jason Segel, Mila Kunis and Jonah Hill - as celebs whose secret romance was just uncovered (to the heartbreak of her ex-boyfriend).

However, following accusations of rape, sexual assault and emotional abuse against Brand in a documentary - accusations he’s fervently denied - prior comments about his behaviour across his career have started resurfacing.

To promote Forgetting Sarah Marshall, Kristen was grilled on Brand’s known sexual lothario image of the time, and how that tied into his role as sex-crazed rockstar, Aldous Snow, in the film.

Not one to mince her words, Kristen - who is married to comedian Dax Shepard - declared that he “didn’t try to mess with her or get in her pants”.

“He knew I would lop his nuts off,” she bluntly told the interviewer.

In another chat, she said that she had clearly shut down the idea of any sexual activity with the British star from the outset.

“I made it really clear from the beginning that I would sock him in the balls if he tried anything. So he was intimidated,” she said.

However, in a chat with Empire magazine, Kristen acknowledged Brand as a “gentleman” during sex scenes.
