The duo was greeted by screams from Reid and other celebrity contestants including David Hasselhoff's ex-wife Pamela Bach.

Mintz-Plasse and Yelchin offered up tickets to an in-house screening of their new horror film remake, with the winners of the task, including American Pie star Reid, landing places at the showing.

The actors set an additional challenge for one housemate to earn a ticket - by eating a garlic kebab.

British pop star John Grimes accepted the task and Mintz-Plasse joked, ""I kinda wanna see some puke!""
