Sexy Stars: Kate Moss, Gigi Hadid stun in hot styles

Talk about model behavior ...

Kate Moss, 42, proved she's still got it this week when she flaunted her slim legs in a ultra-short black and white minidress and adorable Mary Janes. Taking a cue from her predecessor, model-of-the-moment Gigi Hadid, 21, turned heads in an asymmetrical second-skin nude dress with sexy ripped slits that crept up her thigh.

Hadid's 19-year-old younger sister, Bella, opted to show off her flat tummy in loose track pants, white sneakers and a Nike cutoff tan, proving that casual can be sexy, too.

But it wasn't all about the models this week. Actress Olivia Munn, 35, wowed on the red carpet in a camel halter crop top and a shimmery, scale-like ankle-length pencil skirt that reflected the turquoise carpet.
