The world's most hated celebrity is apparently also its most beautiful. 

A week after landing on Star magazine’s list of the 20 Most Hated Celebrities in Hollywood, Gwyneth Paltrow has rebounded with People magazine's World's Most Beautiful accolade. The 40-year-old Goop founder, best-selling cookbook author, and star of the upcoming "Iron Man 3" film, says she is less glamorous at home than in public. 

"Around the house, I'm in jeans and a T-shirt. I don't really wear makeup. That's what they're used to," she tells People. As for her husband, Chris Martin, "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." 

One thing Paltrow isn't shy about admitting is the time she puts into keeping her health and body strong. 

"It makes me look younger and feel strong," says the actress, who does the Tracy Anderson Method five days a week. "When I first started, I thought, 'I'll never be good at this. This is a nightmare!' But now it's like brushing my teeth, I just do it." 

And for those who do not worship at the altar of Goop (Paltrow's digital media and e-commerce company), just what is the Tracy Anderson Method? At its most basic level, it's a routine created by ex-ballerina Tracy Anderson that emphasizes repetition via a series of dance-based workouts. Similar to the P90X routine, this is something that can really be done anywhere, without the use of weights or machinery. 

"Tracy's very honest," Paltrow told Redbook in December. "I was like, "I know. I've been doing yoga for seven years, I'm trying Pilates, but this is just my shape; I can't change it." She's like, "Oh, no, I'll get that right off you." I started working with her and lost 11 inches! That's actually standard for her. I couldn't believe it."

Yeah, OK, but we all can't live the celebrity lifestyle. Is Anderson's method practical? According to a review by the site FitBottomedGirls, you'll get results, but the routine is not for everyone. 

"Definitely not for beginning exercisers or those who dislike dancing," the site says. "These DVDs are unique and get you to feel the burn, but with no scientific backing, little instruction and too many eye-rolling moments, they just can't get the full FBG stamp of approval."

But hey, others swear by it, so be sure to check around, examine Tracy's site, and come to your own conclusions.
