Sacha Baron Cohen walks Grimsby premiere red carpet in his undies as wife Isla Fisher feeds him hot chips

It's been 10 years since Sacha Baron Cohen sported a lime green mankini for Borat.

And now, he's ditched the trousers again to promote his latest role as the dim-witted Nobby in Grimsby.

Watch the footage above to see the actor strutting the red carpet for the film's London premiere in full character…complete with a beer-stained shirt and revealing baggy underwear.

Keep watching to see his wife Isla Fisher feeding him hot chips as four of his nine onscreen lout children arrive in character, with beers in hand. We hope there's juice in those beer cans, kids!

Grimsby, which follows the story of the perpetually unemployed Nobby and his girlfriend (Rebel Wilson), hits Australian cinemas on March 10, 2016.
