Good thing this kind of plastic doesn't melt!

Janice Dickinson is 56 and still rockin' it in a two piece bikini! The former supermodel, wearing a sexy red and orange bikini, looks better than some women half her age ... even if she's admittedly had help from a surgeon's scalpel.

Ms. Dickinson is now dating British writer David Blakely who is 24 years her junior. You go, girl!

See more of Janice on the beach in Malibu ... after the jump.
