InStyle.com Presents: Stars at Home

Superstar singer Josh Groban resides in a breezy Malibu bachelor-pad, set on two acres of beautiful tree-filled hillside. "When I first saw this place, my reaction was, 'It's like being on an instant vacation -- I'll take it!" Groban says. The home has a pool and waterfalls, as well as a wood-paneled media room where he hosts movie nights.

Jessica Alba

"The energy here is so inviting -- it is open and playful," says Jessica Alba of the two-story, eco-friendly L.A. canyon home she shares with husband Cash Warren and one-year-old daughter Honor Marie. The actress worked closely with eco-design enthusiast Kari Whitman to create the look. "It's all about working with existing things," says Whitman. "Jessica would e-mail me things she found on Craig's List."

Miley Cyrus

The two-story, 9,000-square-foot Cyrus-family North Hollywood home is like a villa with its red-tiled roof, hacienda-inspired architecture, Tuscan-like fountains and swimming pool. "Parts of it are really modern, but it's mostly old Italian country," says Miley Cyrus. A temperature-controlled wine room was turned into a haven for dad Billy Ray's guitar collection.

To keep the family of five happy, "90210" star Jennie Garth and her actor husband Peter Facinelli strive for a balance of style and functionality in their 9,500-square-foot Los Angeles home. Some rooms are clean and classic, while others, like the game room, are definitely for play. "The furnishings reflect Jennie's personality," says decorator Trina Boyd. "Romantic, soft and pretty, with a little bit of edge."

It has history! The original house was once home to country-western star Tex Ritter (father of John Ritter). "One of our neighbors said he used to see John Wayne coming to the house for poker games," says Facinelli. (Photo: Bobby Fisher)

Kelsey Grammer

Kelsey Grammer's 8,000-square-foot New York retreat -- set on two-acres of coveted coastal Hamptons property -- is all about relaxation for his family of four. The decor of the classic New England-style home is a mix of west coast and east coast, as well as a mix of Kelsey and his wife Camille's tastes. "We've grown together toward a certain style," he says. "Without Camille I would never have become a guy who cares about furniture. Now she just has to figure out how to accessorize me, so I go with everything else in the house!"

Why He Loves It

There's room for a crowd. The estate has seven bedrooms to accommodate Grammer's extended family for dinners and parties. "I like knowing everyone is just down the hall," he says. (Photo: Paul Costello)

Michael Kors

Fashion designer and quintessential city man, Michael Kors and his partner, Lance Le Pere, share a sophisticated apartment in the iconic West Village neighborhood of Manhattan. Along with architect Glenn Gissler, the couple transformed their modern, minimalist apartment into a home. "We wanted to be surrounded by elements of sleek, classic interiors by George Nelson, Mies van der Rohe and Knoll, and give a little wink to the seventies because that's when I think New York was so much fun," Kors says.

Amy Smart

"It's Cape Cod meets Hollywood bungalow," says actress Amy Smart of her 2,000-square-foot, two-bedroom cottage in Beverly Hills. Special touches like a vintage farm table in the kitchen and crown moldings in every room pull together the charming decor. "I didn't go too modern because I wanted to keep the feel of the '40s," Smart says.

Why She Loves It

A large backyard full of rosebushes and lemon and lime trees surround her saltwater pool and deck. "I grew up in a house with huge decks and picture windows," Smart says. "I still need that touch of nature to ground me." (Photo: Art Streiber)
