Lovely Lea Michele took the plunge at the Los Angeles premiere of New Year's Eve, stealing the thunder from the red carpet veterans. The Glee girl showed off her gorgeous goods in a dramatically lowcut Valentino sparkler, which she paired with Christian Louboutin heels and Neil Lane bling. Also dressed to thrill at the star studded premiere, was Fergie in a mirrored Monique Lhuillier cocktail dress, Hilary Swank in Elie Saab and Katherine Heigl in Dolce & Gabbana.
