Raquel Welch & More Age-Defying Beauties Hit Hollywood

Raquel Welch was every man's fantasy when she starred in "One Million Years B.C." way back in 1966 -- and 46 years later, she still looks H-O-T.

Welch, who was 26 when she donned that now-famous fur bikini, was spotted last night at the Vanity Fair Montblanc party at the Hotel Bel-Air Los Angeles.

With a tight gold dress and some crazy big (and probably fake) hair, Raquel looked pretty great for 71-years-old.

She wasn't the only ageless wonder at the party either -- Cheryl Tiegs, 64, and Jackie Collins, 74, both looked fab as well!
