"It was really beautiful. It was a little punk-y. She's just so pretty, it's abnormal."
The actress - who has daughter, Apple, eight, and son, Moses, seven, with her husband Chris Martin - recently beat off stiff competition from the likes of Amanda Seyfried, Jennifer Lawrence, Pink and Halle Berry to receive the annual honour of being named the world's most attractive woman.
But she previously insisted that if people could see her at home in her casual clothes they wouldn't think she was so beautiful.
She said: "Around the house, I'm in jeans and a T-shirt. I don't really wear make-up."
If she ever does opt for glamour at home then her rocker husband will make fun of her.
She added: "He'll make a joke about it. If I've gotten fully dressed up, he'll be like, 'Oh, wow! You're Gwyneth Paltrow!' Because he's used to seeing me in like baggy shorts and frizzy hair."
