Summer's Hot Bodies
"I don't think I look pretty when I'm made up," says Jolie (on Jekyll Island, Ga., where she vacationed with son Maddox in May). "I do feel beautiful when I'm in the middle of nowhere and I'm sweating and I'm tired and I'm working really hard—or when I'm just being a mom."
Knee surgery in June sidelined the future Mrs. Kevin Federline's concert tour, but it did give Spears more time to focus on romance—and wedding planning. The couple warmed up their honeymoon skills on Maui (left) in July.
After her daily two-hour workout on the courts, the tennis champ hits the beach. "I like to surf or just take my guitar and play," says Williams (in Malibu), who will compete in the U.S. Open this month. "My trainer wants me to have more muscle [but] I like my body the way it is."
Sure, Aniston (in the South of France in May) has "a body that rocks the world," as one pal put it, but that doesn't mean she starves herself. "How are you supposed to live on grapefruit?" she says. "Please."
Sandra Bullock once said, "Matthew looks gorgeous naked. He should be naked as much as possible until things start falling." As he demonstrated in Spain in April, that time is: Not yet.
U.S. SWIM TEAM
Just add water: Fast guys in small suits, Americans brought home medals by the chestful
Six-feet-four and 194 lbs., he's hefting eight medals (six gold, two bronze) home to Baltimore, along with a big appetite. "The other day I had like seven McDonald's double cheeseburgers," says Phelps, 19. "I'll probably put on a few more pounds when I get home."
Phelps shared 4x200 freestyle gold with (from left) Klete Keller, 22, Peter Vanderkaay, 20, and Ryan Lochte, 20. "I'm trying to not let the attention get to me," says Lochte. "We had a couple of girls who wanted us to sign their arms. I thought that was kind of weird."
The 50m freestyle winner and member of the bronze-winning 4x100 freestyle-relay team trains by tying cinder blocks to himself and seeing how far he can swim in one breath. "It's called a brick-kick," says Hall, 29. In all, he has cemented 10 Olympic medals.
The swimmer will return weighed down with gold for the 100 and 200 backstroke and the 4x100 medley relay. But he does play favorites. "The 200m is my baby," said the 21-year-old, who won silver in Sydney. "That medal means the world to me."
JUSTIN TIMBERLAKE & CAMERON DIAZ
That tan, the toned muscles, the washboard abs—yep, it's Diaz, confident enough to wear the world's smallest bikini while surfing with her guy Justin Timberlake off Maui.
The singer says performing "is the best cardio." Another great way to get the heart pumping? Taking a flying leap off a high-dive platform in Monaco—where she vacationed in August with boyfriend Jay-Z.
Fired? Who cares? Looks like the Apprentice star has other things on her mind. Married on Aug. 14, she got carried away by her new husband, real estate broker Ben Moss, in Miami Beach a week later.
The actress and nightlife staple relaxed while visiting Las Vegas with the Hilton sisters. Asked recently about rumors she'd had breast implants, Reid said, "It's just a push-up bra."
JULIO IGLESIAS JR.
A singer like his father and younger brother Enrique, Julio showed off his abs and other muscles on an August holiday in Marbella, in his native Spain.
Taking a plunge with Ocean's 12 costar Matt Damon off the Warner Bros. yacht in Villefranche, France, Brad Pitt gave the locals something to Ooh la la! at in May. His six-pack incentive? Turning 40. "It's amazing what an impending midlife crisis will do for you," says the actor. "It got me motivated."
