Raquel Welch, 76, is smokin' hot at Beverly Hills fundraiser for Farrah Fawcett Foundation

Forget everything you've heard about age-defying serums and the perfect diet. We all just need to copy whatever Raquel Welch has been doing for the last 40 years.

The grade-A bombshell stepped out Thursday night at a Beverly Hills event for the Farrah Fawcett Foundation -- and we're having trouble believing she's really 76 years old. Sporting a sexy beige ensemble, a Dolce & Gabbana belt and perfectly-coiffed hair that would make Farrrah proud, Raquel is clear proof that age is definitely just a number.

First, take a look at Raquel during her younger years, as an iconic sex symbol of the 1960s and '70s:

8/23/1966-Rome, Italy-ORIGINAL CAPTION READS: America's latest entry into the 'Sex Goddess' sweepstakes is Raquel Welch, whose long brunette hair and captivating eyes appear to give her an excellent chance to win the title. A trim 37-22 1/2-35 1/2 figure won't hurt her either, and the 23-year-old Miss Welch has already begun a movie career. Her latest film is 'Shoot Loud, Louder -- I Don't Understand,' for Joseph E. Levine.
