Kate Hudson isn't ashamed of admitting that she enjoys eating fast food, but could this be here secret to her unwavering beauty and curvaceous body?

The "Wish I Was Here" star attended Goldie Hawn's charity event in Beverly Hills last Friday and she gushed about her beauty secret to the press on the red carpet.

At 35, Hudson is really physically fit, but what she told the media about the foods she loves to eat may be a shocker to many. For one thing, the "How To Lose A Guy In 10 Days" actress dished that she loves feeding herself with "real double double burger, fries and Coke," reports Us Weekly.

Interestingly, despite the Fabletics designer's craving for fast food, she said that she maintains her fit and curvy physique by working her "ass off."

She even admitted that she allots some time in the gym to ensure that her body looks and feels great.

"You [have to] work your ass off, that's the only way. [And] you have to eat right," Hudson said. "Everybody wants some sort of secret and there just isn't, it's just you have to work out."

The Golden Globe-winning actress shared that she's been an avid Pilates practitioner for fifteen years now, and she noted that she's very consistent when it comes to working out.

"I wouldn't say [I work out] a lot, just consistently...People think for some reason you have to work out for two and a half hours...but, it can be little. It can be 20 minutes, it could be 40 minutes, but you have to [get it in]," she said.

"You can't do like two weeks and go like do two days and then take a week off and then do three days and then go, 'Why aren't I [seeing results?] I don't get it.' You know, you just got to do it -- sad, like anything else in life!" she quipped.

Apart from hitting the gym and doing Pilates, the "Almost Famous" star also dished to Shape magazine recently that she does body cleansing every once in a while.

"I've eaten in all sorts of different ways over the years. I like to do juice cleanses twice a year for five to seven days, or food elimination cleanses where I just eat super clean," the blonde beauty said. "Other than that, I eat everything. I just love food. I love bread. I love pasta."

Interestingly, Hudson also shared what she and her family are planning for this Thanksgiving, according to E! News.

"It's about 20-plus of us all together," she said. "We watch football with the kids."

So is his British rock fiance Matt Bellamy joining them? Hudson said, he is going to watch football with them, adding, "But ya know, they have another kind of football. But he's up for anything."

When asks which team she's rooting for, Kate smiled and said, "I'm a big Peyton Manning fan. We grew up in Colorado so when we moved to Denver it was heaven so obviously I'm rooting for the Broncos."
