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.

Janice Dickinson never misses an opportunity to strike a pose for the cameras. While filling up her SUV in Brentwood, the self-proclaimed world's first supermodel was happy to flash her rail-thin frame while holding the pump.

The 56-year-old brunette, wearing a skimpy lilac dress and heels, has been extremely vocal over the years about her plastic surgery procedures. Looks like Janice has been able to maintain her skinny bod ... even if a doctor or two has helped her out!

Ms. Dickinson recently had an incident involving her false teeth. She tells Page Six:

"I was so excited talking to [my friend] that I put my teeth in my napkin, and then I couldn't find them! Did they fall into the soup? These things are so expensive they could feed a small village."

How embarrassing! See more of Janice at the pump ... after the jump.

Plastic surgery aside, Janice Dickenson looks pretty darn good ... even without makeup!

After completing a round of Celebrity Rehab with Dr. Drew, it seems like Jan made up for recent slip-ups in her sobriety, dumped some emotional baggage, and got back on track and she's looking better for it!

Now normally Naomi would win this face-off hands down, but we were as shocked as anyone to see Janice Dickinson looking, well, great yesterday in a patterned mini!

Naomi looked appropriately gorge at Nobu in New York for dinner with her Russian billionaire boyfriend, and we're not sure what Janice was doing at the SLS hotel, but whatever it was, it certainly made her look better than she has in years!

We can hardly believe that Janice is 15 years older than Naomi. And that's a compliment to her doctor!

Former supermodel Janice Dickinson was spotted at a BBQ in Malibu on Labor Day, and we caught her munching on some food as she strutted around in a skimpy bikini. Hey, for 55 she looks pretty good, right? But maybe she should tone down the tanning sessions a little bit...she's toastier than a hamburger bun that's been left in the oven for a few hours!

The World's First Supermodel, Janice Dickinson, may be 55, but she's still got the body of a 20-year-old... probably because most of her parts are just 20 years old!

Fresh out of Celebrity Rehab, Janice appeared relaxed and tanned and to be enjoying the company of her much younger friend!

But is he a friend with benefits?

Closer Magazine

Celebrity Rehab resident and the world's first supermodel Janice Dickinson is showing off her 55-year-old body in a naked photo shoot for Closer Magazine.

"I love my body, but it's a compulsive obsession," admits the plastic surgery fan.

"There's no such thing as too much. Whatever it takes to make an individual feel better, I'm all for it," Janice says. "I'm going to be the best looking corpse on the planet!"

Janice is currently shooting season four of Celebrity Rehab. The former ANTM judge checked herself into Dr. Drew's facility for alcohol addiction.

Celebrity Rehab's newest resident Rachel Uchitel took a break from a nice therapeutic game of bowling yesterday to get some advice from fellow rehabber Janice Dickinson.

We can't imagine what words of wisdom Janice was imparting on her younger lookalike (maybe what plastic surgeon to use in LA?) but it looked like a deep and intimate conversation ... until Jason Davis walked in on them:

P.S. What happened to his arm?
