While you and I cleaned out the pool, braved NorthPark Mall in Dallas, or invited friends over for BBQ and margaritas, the rich and famous played quietly at their second homes. I mean, who got this whole second home fad started anyhow –celebrities and the very wealthy. William Randolph Hearst built his Hearst Castle in San Simeon with 41 bedrooms so he could invite friends. I mean, what fun is 95,000 square feet if you live there alone and can’t fill it up?

In Telluride, Colorado where Seinfeld has his second home mansion, the home is often filled with friends. Others, however, like to take to the beach for a quiet get away with loved ones. Of course, Dallas quarterback and newlywed Tony Romo tried that this summer — at Sean Payton’s Watercolor, Florida beach house — and ended up playing football on the beach.

But there is no doubt that when one prominent figure’s private island retreat recently made international headlines, it was time to take a closer look at these getaways and maybe whip out the checkbook. Celebrities bring panache to a second home community and usually help raise property values, voyeurism as well as the fun. Here are a few spots where the celebs hang out on holidays:

Malibu — Goldie Hawn and Kurt Russell
0 Broad Beach Rd, Malibu, CA
Value: $14.75 million
Bedrooms / Baths: 4 / 5
Square Footage: 4,300

This gorgeous ocean-front home is done as a Balinese-styled getaway on already celebrity-studded Broad Beach. If you cannot afford the $14.75 million asking price, never fear. You can lease it for a mere $95,000 a month. Wait — just read that the monthly rental has been chopped to $80,000. Wow, that’s way more affordable. The 4300 square foot home was extensively renovated in 2005. Here’s an idea: share between three couples. After all, the home includes three suites (the master bath is more special with a Chinese onyx spa-inspired bath), a Creston media room, a designer kitchen, plus a guest house with meditation or guest room, and a workout room. But really, no matter the holiday, what better place to be than Malibu?

Kelsey Grammer
256 Tall Timber Rd, Avon, CO
Value: $9,950,000
Bedrooms / Baths: 6 / 8
Square Footage: 9,743

Kelsey Grammer, the former “Cheers” TV show star, is selling his enormous mountain ski retreat that was once proudly featured in Architectural Digest.

Grammer had only skied about two years when he bought the house, located in between Glenwood Springs and Breckenridge.  But who cares about powder conditions when you have a wine cellar, stone flooring, vaulted ceilings, nanny quarters, deck and well, this house? The structure’s building materials are recycled and have an intriguing history. The hardwood was salvaged from an 18th-century Chicago warehouse.

Martha Stewart
Mount Desert Island, ME
Bedrooms / Baths: unavailable
Square Footage: 35,000

Martha Stewart has been a summer resident in Seal Harbor for more than ten years. As they say in Maine, this is where she “summers”. This amazing second home is on 63 acres, called Skylands, and was originally built for automobile tycoon Edsel Ford in 1925. The magnificent grounds were designed by Jens Jensen. Despite the home’s age, Martha is only the third owner. As you can imagine, the home has absolutely everything including a flower-arranging room! As for what she paid for the historic home, all we know is what Martha reportedly told The New York Times: “I won’t even say the price, but you can say it was one of the best purchases of property since the Louisiana Purchase.” Good for you, Martha! That great negotiating — and we are sure Martha did most of it — even included the antique cars and original furniture. No SubZeros up here –even the refrigerators (above) are original, and Stewart reports they are working just fine: “You can put a whole cow in them. They’re fabulous.”

Now here’s something we just cannot believe: according to Internet gossip, Stewart is not fond of tresspassers and supposedly has the stones on Skylands’ pink granite drive annually removed, washed, and then replaced. Why not just let the ocean shower them with saltwater?

Ozzy and Sharon Osbourne
Malibu, CA
Value: $9.5 million
Bedrooms / Baths: 5 / 5
Square Footage: 4,500

The Osbournes bought this seaside home in 2003 for $5.1 million.

We hear that Ozzy and Sharon Osbourne have been shedding real estate lately, such as the home featured on their reality series— which was later sold to Christina Aguilera—and also their main residence, a mansion in Hidden Hills, Calif. Sadly, the Osbournes have also been trying to sell or rent out a gorgeous midcentury beachfront home for years. The rent has varied from $25,000 and $40,000, that’s per month. The home is loaded and features a library, walk-in closets, security features naturally, plus numerous beachfront decks and terraces.

Jerry Seinfeld
225 Raspberry Patch, Telluride, CO
Value: $18.25 million
Bedrooms / Baths: 11 / 12.5
Square Footage: 14,200

Comedian Jerry Seinfeld’s massive Telluride, Colo., compound, with 27 acres overlooking Sunshine & Wilson peaks, is on the market fully furnished, often the case with second homes, is being offered fully furnished. The mansion was completely renovated circa-1991 and includes a wet bar, lofts, and a huge guesthouse. But the sweet spot is truly the outdoors. If you can visualize a deck twice the size of most homes, that would be the 5,500-square-foot deck. Talk about great entertaining. The property also includes hiking trails and a creek, and is of course located smack near some of the best skiing in the state of Colorado.
