Eddie Redmayne may be one of the UK's most bankable film stars, but he revealed he still loses it when he meets a big name.
The Oscar-nominated Theory Of Everything actor told a US chat show how he and his wife "stalked" Jennifer Aniston at a party.
Eddie, 33, told Jimmy Kimmel Live! that he was like a "kid in a candy store".
The Brit star said: "My wife (Hannah Bagshawe) and I love Friends... and so we saw Jennifer Aniston at a party and we were just incredibly inappropriate.
"We so wanted to meet her that we sort of literally stalked about four metres behind her for an entire evening."
He said: "Eventually she was like, 'Okay!' So we got to meet her and she was as beautiful and wonderful as you'd expect her to be."
He admitted: "She could have turned around and slapped us for being stalkers."
Eddie also told how meeting Julia Roberts, who presented him with his Best Actor gong at the Screen Actors Guild Awards, almost scuppered his acceptance speech.
He said: "My dad's favourite film is Pretty Woman, so as a kid, I think at an inappropriate age, I was watching Pretty Woman.
"So this moment happens when your name gets read out and it's such a sort of extraordinary euphoria and it's kind of white noise, it all goes into a sort of blur.
"Then suddenly, there I was hugging Julia Roberts. And then I was meant to be articulate and all I could think of was, 'I wanna tell my dad!' It was amazing."
