Uh-oh! Paris Hilton was arrested for alleged cocaine possession over the weekend, but if she's guilty of anything, it's taking an arrestingly gorgeous mug shot (above right)!

After Las Vegas police reportedly found cocaine in Hilton's purse, the hotel heiress was booked into the Clark County Detention Center in the early morning of Aug. 28, reports People, and posed for this gorgeous head shot.

Wearing pink lip gloss, perfectly mascaraed eyelashes, and her blonde hair adorned with a sweet braid, Hilton looked positively coquettish as she gave the camera a coy smirk.

It's not surprising that Hilton looked super-glam in her snapshot -- according to Us Weekly, she had her tresses tended to at COLOR: A Salon by Michael Boychuck just hours earlier.

This isn't the first time the 29-year-old Tease perfumer has taken a mug shot that looks like an outtake from a magazine cover shoot.

Arrested in September 2006 for reckless driving, she made love to the camera by giving it a seductive sideways glance (above left). Nine months later, she was again photographed (above center) just before she began her brief jail sentence. For the latter, it looked like the hotel heiress brought in a full hair and makeup crew, her face perfectly primped and her locks draped to the side in loose waves.

One thing is for sure: If we at StyleList ever get arrested, our first call won't be to our lawyer but to Hilton, who will hopefully share some quick tips on how to take a killer prison pic.
