Emma Stone thinks Willem Dafoe is an alien

Asked on the Late Show which celebrity she thinks is most likely to be an alien secretly posing as a human, Emma swiftly replied: "Willem Dafoe. Hundred percent."

Host Stephen Colbert replied: "You did not have to think about that very long."

But the Cruella actress insisted Willem was an obvious choice.

She said: "It's so simple. I mean, don't you - of course.

"If it was like, Willem Dafoe's actually an alien everyone would be like, 'Yeah! Obviously. And a great one!'

"Like, if they're all like Willem, bring 'em on! Land upon Earth, please!"

Stephen said: "He's an alien in a very well-fitted man suit."

Emma added: "My favourite alien."

The actress shaved her head for her role in Bugonia and though she wore wigs when out and about in her downtime, she sabotaged her own attempts not to draw attention to her hairpiece.

She said: "I'm so unsubtle and just generally stupid that I was like... the wig looked good, but the whole night I was like, 'Can you tell it's a wig?'

"To everyone! And they were like, 'We're pretty sure she's wearing a wig, since she moved it around a lot.'"

Emma "misses" her bald look.

She said: "It felt so good. Taking a shower with a shaved head is unbelievable. And every time you're thinking, you really run your hand over your head. I miss it!"

Emma recently admitted she regrets the fact that she didn't show off her bald look publicly during the making of the movie, although she did reveal a pixie cut style at the Golden Globes earlier this year.

The actress told Vogue magazine: "I was bummed I wasn't going out with it. Just straight-up bald. I think that would have been fun."

Emma's close friend Jennifer Lawrence also contributed to the piece and admits that she had reservations about her pal's bold new look after she had made a major hair transformation for her portrayal of tennis legend Billie Jean King in the 2017 film Battle of the Sexes.

The 34-year-old actress said: "I really didn't want her to shave her head. I had already lived through the Billie Jean King haircut."

However, The Hunger Games star was quickly won round when she got to see Emma without her hair.

Lawrence said: "Honestly, (Emma) looked beautiful. She pulled it off."
