"My hair is such a disaster. I never blow-dry. I can't do my hair at all.

really good feet. They're cute!"

For Om-girl Aniston, 39, the benefits of yoga go beyond just a toned bod.

"I've had everything from deep laughter to deep sadness, where I was crying

through moves," she told Self magazine. "It's good to get that

stuff out. You feel like you're having a therapy session, a workout and a

meditation at the same time."

"The gray hairs certainly have come in the last few months," says the

42-year-old of the grey in his anatomy. "The last year has been difficult on

many levels, with the show moving to Thursday night, and everything that

happened this year, and worrying that everything was going to go all right

with the boys [newborns Darby and Sullivan] and my wife [Jill, age 41]. But they've ceased to come in as quickly."

The Oscar-winning actress, now 40, explains how she looks better every year:

"My choices today reflect the way I feel about myself – I'm happier

look is confident and sophisticated, with a bit of an edge but always

comfortable."

The 36-year-old actress says Violet, now 2, her daughter with husband

Ben Affleck, has changed the way the couple looks at themselves. "Ben and I

like more things in ourselves that we now see reflected in Violet. To see my

dimples in her makes me like my dimples because I share them with her."

"Hair to me is not a priority. All I ever do is throw it in a bun," admits

the Grey's Anatomy star, 29. "The only thing I know how to do is

hot rollers, which is sort of over. I can't style bangs even though I love

them and I'm always like, 'Let's cut some bangs!' And then I'm stuck with

hair I can't figure out."

"I can be pretty vain. Vanity's not so bad," admits the 38-year-old. "Look,

do I work out because I like to look good? Yes, that part's vanity. Do I

work out because it makes me feel better? Yes, and that's not vanity."

The actress and singer has one straightforward beauty goal: "I like to look

good for Marc," she says of her husband, Marc Anthony. As for her beauty

routine? "I don't use a lot of expensive creams," says Lopez, 38. "It's more

simple: mild cleanser, sunscreen and lots of water.

"People in L.A. look too good to me. It's important to keep flaws," the

39-year-old Aussie says. In fact, the Lucky You star says his

best look comes purely by accident: "I look my best when I take my helmet

off after a long motorcycle ride. I have a glow and a bit of helmet hair."

"When I first started meeting with agents, I remember one immediately

telling me all the things I had to change: I'd have to get my teeth fixed,

lose weight," remembers the 31-year-old actress, who starred in last year's Fantastic

Four: Rise of the Silver Surfer. "Then I met with another agent two weeks

later who was like, 'You're perfect – let's start.' That's a good rule

to follow: Go where the love is."

Fall Out Boy bassist Pete Wentz, 28, admits that his sexy "guy-liner" look

is assisted by his hard life on the road. "I get a ton of under-eye circles

because I don't sleep. Usually I'll just put on more eye makeup and let it

blur in."

The serene Queen explains how she stays sexy at 62: "Number one, I have

never smoked. When you are young, you seem indestructible. As you get older,

you realize how much it's helping you. I've never done anything to excess,

really." She also thanks her "fundamentally sunny nature," saying,

"unhappiness etches itself on one's face very quickly."

"Some people are effortlessly glamorous and sexy," the actress, 32, has told

PEOPLE. "For me, a lot of that stuff is difficult." Still, her skin-care

regimen sounds pretty easy: "I just wear a lot of sunscreen. That's it.

Nothing more. I'm just lucky my grandma gave me great skin."

The 35-year-old star of Prison Break reveals the downside of

having a shorn identity. "I've been shaving my head on and off for years,

but for a low-maintenance look, it takes a lot of maintenance – I have

to cut it twice a week!"

"I had a couple of freckles on my face that I didn't like, so I had them

removed," admits the 25-year-old country star. "And I remember one kid said,

'Now I can't play connect-the-dots on your face anymore!' I'll never forget

that."
