In the words of Rihanna, where have you been?

Heather Graham came out of hiding on Monday as her and a friend decided to do lunch in Hollywood and she still has that gorgeous smile!

The 42-year-old actress has been relatively under the radar since her appearing the hit comedy The Hangover, but that might soon change as she's set to reprise her role as Jade in The Hangover Part III. Nevertheless, it's great to see her in good spirits!

Good genes or a good doc?

Whatever the reason, we just can't believe Heather Graham (aka Rollergirl) is 41-freakin'-years-old!

The actress, who's been working steadily since the late 80's, flashed us a smile as she left a lunch in Beverly Hills on Friday.

Even though Graham played a stripper who married Ed Helms' character Stu in a Vegas wedding in The Hangover, unfortunately, she won't be returning for The Hangover II, which features Stu's bachelor party in Bangkok.

Heather Graham is vacationing in an itsy-bitsy teeny-weeny pink bikini with her boyfriend Yaniv Rav in Ischia, Italy, and we have just two words for her:

Thank you.

Can you believe this woman is 40? I guess it helps that her boyfriend is about six years younger. Plus it seems she keeps herself fit by doing this:

Hey, we all have a case of the crazy eyes sometimes! And both Heather Graham and Jared Leto were afflicted last night during the chaos that was the Golden Globes.

Think Leto will ever be a movie star again? If Graham can bounce back with a hit like The Hangover, anybody can!

Heather Graham showed up to the 2008 National Board Of Review Of Motion Pictures Awards Gala in NYC last night, and she nearly set the red carpet on fire! It's hard to believe that the actress is going to be 39 this month - she doesn't look her age at all!

Let the Halloween costume hunt begin! October 31st is just around the corner, so this is the last weekend to finish shopping... but if you're outta ideas of what to wear or who to be, take a cue from some celebs last year:Remember when Paris wore more than one classy outfit, Lindsay got physical and Brandon Davis dressed as, uh, firehead? Good times!

Still not sure? Well, we have one final costume suggestion below the cut...

Bikini season may be a thing of the quickly-receding past, but don't worry - party season's just starting up! Lindsay Lohan certainly got into the spirit, parading through the throngs of guests in attendance at the Chateau Marmont dressed as, um, not a whole lot in particular, but she was far from the only one - in addition to Heather Graham (who looks a lot better in motion than in the stills we posted earlier), the party saw the sudden appearance of magician David Blaine!
