Eddie Redmayne's wife wants him to gain weight.

The 'Theory of Everything' star admits Hannah Bagshawe - who he wed last month - worried he looked underweight in some recent pictures so urged him to gorge on calorific foods.

He said: ''My wife saw some photos of me at the L.A. premiere, and she's like, 'Ed, you're looking underweight.'

'I said, 'Baby, I've got loads of sushi and juices.' And she was like, 'That's not what I'm talking about! I'm talking a f***ing gigantic bowl of spaghetti Bolognese and a burger.' '' ​

The 33-year-old star admitted he has few hobbies when not working and claims he isn't particularly good at the things he tries.

Speaking to Jennifer Lawrence for Interview magazine, he said: ''What do I do? I don't know. I'm really s**t at the piano. I play the piano. I occasionally try to pretend to paint, again, badly.''

And Eddie confessed that his biggest passion away from work is watching reality TV shows.

He admitted: ''I come home from trying to pretend to know about astronomy and physics all day and turn on 'The Real Housewives.'

''I've been a closet lover of faux-reality TV since 'The Hills'. It's bad. I can't believe the intricacies of their lives. I want to know how much of it's a sham, how much of it is directed.

''I'm also a complete sucker for the soundtracks, the teeny pop music.''
