Kate Hudson has a new claim to fame.

The 29-year-old divorced single mom and daughter of Goldie Hawn heads the list of People magazine's 100 Most Beautiful People.

The actress, who says her 4-year-old son leaves her short on beauty sleep, wasn't always a glamour girl.

"I was a tomboy. I had three brothers. I was the girl with the dress on that always came back in the house filthy with scrapes and bruises. But I was always very girly. I had to be able to twirl so that my underwear showed," she says.

Her best time for looking good, she says, comes "at the end of the night, when everything's soaked in and I'm still up. I like the leftover makeup in the morning. You've got to wash your face but there's always the leftover eye makeup, I love that."

Hudson, who was nominated for a best supporting actress Oscar in 2001 for "Almost Famous," is rumored to be dating her ex-boyfriend Owen Wilson. She and rocker Chris Robinson divorced in 2007.
