Star Style Latest - Cat's Been at the Hairspray and Sienna Does Letterman

After a relatively celeb-less UK premiere last week, the LA Hairspray premiere was an altogether more star studded affair, with the full cast plus other celebrities taking to the red carpet.

Female leads Michelle Pfeiffer and Amanda Bynes both turned out looking stunning in similar pale coloured bandeau dresses. Michelle chose a slim-fitting belted cream number and could have passed for Cameron Diaz's older sister with her age-defying figure and beach babe blonde locks . Teen star Amanda meanwhile opted for a more voluminous off white frock, worn with strappy gold heels and a deep tan.

Our real star of the evening, however, has to be Cat Deeley. Since leaving good old Blighty for sunny LA she's been endearing herself to the American public, and with outfits like this one we can see why. The Brummy lady looked stunning in a shimmering gold sequined dress worn with strappy tan sandals, a thick gold bangle and big teardrop earrings. Our love affair with Ms. Deeley continues...

Meanwhile over in New York, Sienna dropped in on the Late Show with David Letterman looking as fabulous as ever. Upon arrival she modelled a beautiful full dress from the Twenty8Twelve collection she designs with her sister Savannah, which will be stocked online at ASOS.com from the end of August (we've had a sneaky peak at the collection and it's as amazing as you'd expect!). On leaving the studio, it was all change as she stepped out in a figure-hugging black dress and a pair of black ankle strap sandals. We're pleased to see she's scrapped the full-on eyebrows she sported this weekend!
