The Glee star looked bronzed and fabulous as she posed on the blue carpet, parading her pins in a teeny tiny thigh-skimming outfit.
We have to admit we loved Lea's dress - the starlet opted for a gorgeous jewel-toned number by Blumarine complete with a wrap-over skirt covered in an oriental floral pattern.
She also appeared to be going bra-free for the occasion, instead flaunting her décolletage thanks to her frock's eye-wateringly low neckline.
The actress accessorised with a dainty silver body chain and rose gold peep-toe heels, styling her brunette locks in long, tumbling curls.
She mixed things up on the make-up front, ditching her usual nude lip for a pink glossy pout teamed with bronzed cheeks and lashings of mascara. Gorgeous!
Lea also did some mingling with her fellow celebs at the fancy event, bumping into fellow brunette beauty Zooey Deschanel.
And with two famous gals in one place there was only one thing to do - snap a selfie, of course!
