Felicity Jones, who stars as Stephen's first wife, Jane Wilde Hawking, in "The Theory of Everything," admits she's been charmed by the world renowned theoretical physicist.

The 31-year-old actress shared: "He has such a dry sense of humour... He has a real rockstar energy... He had seen a screening of the film... and afterwards he was like 'Can we go to to a nightclub? Let's go out and party!' which I love!"

Felicity also revealed how she learned she'd been handed a Best Actress nomination for her part in the film, which also stars Eddie Redmayne.

She told "The Jonathan Ross Show": "You are told you'll get a phone call at 5.30am. I just thought I'll sleep through it, I wasn't really expecting a nomination... I thought, 'It's fine, I'll wake up at 10 a.m. and it'll all have happened and I'll probably be commiserating' ... so I can just spend the day in bed."

"But then I woke up at about 4 a.m., just sprung up ... So I just nervously waited then I got a phone call saying I'd been nominated."

Asked how she felt when she received the news, Felicity said: "There were no words. There was just lots of hyperventilating and exclamations and screaming and jumping around in my pyjamas."
