How to Stay Beautiful At Any Age

Christie Brinkley is still stunning, and Teri Hatcher makes 42 look like 30!

Only “Extra” knows how Hollywood’s hottest stars shine well into their 40s and 50s, as they reveal their tricks in “The Black Book of Hollywood Secrets.”

Beautiful “Housewife” Teri Hatcher’s secret? She pours a cup of red wine into her bath to help soften her skin. To wipe wrinkles away, Teri told us, “I use Hydroderm, a collagen kind of thing.”

For 40-year-old supermodel mom Cindy Crawford, a mix of milk and water misted on the face eschews a dewy fresh look, while Kim Basinger, 53, uses a petroleum-based scuba diving sunscreen to keep her skin soft.

If you want to look 10 pounds thinner instantly, rub cellulite cream into your jaw line, which will suck the water weight right away.

Christie Brinkley credits her timeless beauty to plenty of sunblock and a healthy diet.

“I’ve been a vegetarian almost my entire life,” she told us.

At 59 years of age, Cheryl Tiegs stays slim thanks to a daily weigh in.

“If I'm one pound or two pounds overweight, I put on the tightest pair of pants that I have; it reminds you to loose weight before it gets out of control,” Tiegs confessed.

Angela Basset, who is still sizzling at 48, also shared her beauty secret.

“A sincere smile from a pure heart is the sexiest thing a woman can have,” she admitted. “In European countries they've had an appreciation for the confidence and the allure of a more mature woman, and we are finally coming around to that.”
