Matt Smith has bulked up to improve his morale.
The 'Doctor Who' actor - who plays the titular Time Lord in the BBC One sci-fi series - has been hitting the gym hard in a bid to improve his physique which has led to him feeling a lot happier about life in London.
He said: "Since I've been back in London, I've been going to the gym three times a week. It makes me feel much better about my life, I have to say. It's just good for my mind."
While Matt has improved his body shape, he insists he still has a long way to go before he gets anywhere near looking like toned actor Ryan Gosling, who is directing Matt's forthcoming fantasy film 'How to Catch a Monster'.
He added to the Radio Times magazine: "I haven't seen his abs yet. He totally wins, he totally wins, mate."
