The Glee cast mates oozed glamour as they struck a pose at the swanky bash, which was held at the Four Seasons Hotel in Beverly Hills.
Gorgeous Lea flaunted her sunkissed glow in a strapless dress by Calvin Klein, complete with cut-out details across her midriff. She added inches to her petite frame with strappy white sandals and accessorised with a boxy clutch.
Her hair was styled in a slicked-back 'do, similar to the look worn by Little Mix's Leigh-Anne Pinnock at the One Direction premiere.
Make-up wise she flaunted mega-watt lashes and petal pink lips, adding a glow to her cheeks with peach blusher.
Not to be outdone, Naya - who recently got engaged to rapper Big Sean - looked positively ravishing in a mega-chic jumpsuit by Pamella Roland.
The 26-year-old clearly wasn't shy of flashing the flesh in her stunning one-piece, which featured a racy plunging neckline and cut-out sleeves.
She added a touch of glitz with a sparkling necklace while teetering along in classic black pointed courts.
Like Lea she opted for scraped-back locks, upping the drama with smoky eyes and a slick of berry lippy.
Loving your style, ladies!
