Ricky Gervais has admitted that his new best friend is a talking frog puppet called Constantine.

The actor and comedian, 52, plays ominously named entertainment manager Dominic Badguy in the upcoming film Muppets Most Wanted.

Speaking ahead of tonight's UK premiere in London, Gervais expanded on his relationship with co-star Constantine, an evil Russian frog who looks uncannily like Kermit.

The film, which sees Jim Henson's creations touring Europe, opens in the UK at the end of this week.

American actor Ty Burrell, who plays French detective Jean-Pierre Napoleon, also confessed to being in awe of his puppet co-stars.
