The Legally Blonde actress made a glamorous entrance at the lavish award ceremony, which was held at the Hollywood Palladium in Los Angeles.
Adding a bold pop of colour to the evening, Reese looked sensational in a satin gown featuring a fuchsia strapless top and a black skirt, complete with a pretty pink panel on one side.
The blonde bombshell kept her jewellery fairly minimal, accessorising with a few silver rings plus a pair of drop earrings, while sporting a low-key sheer pink manicure.
She showcased a gorgeous hairdo too, with the lengths of her golden locks tonged into loose, tousled curls and the roots backcombed for heaps of volume.
For her make-up, the actress shaded her peepers with jet black liner teamed with fluttery mascara, finishing with a wash of peach on her cheeks a slick of rosy gloss on her pout.
The starlet received a nomination at the ceremony for Best Actress for her new film Wild, but lost out to Julianne Moore for her role in Still Alice.
But Reese is also up for the Best Actress gong at the 87th annual Academy Awards, which takes place in LA on 22 February.
Again Julianne is nominated in Reese's category, along with Marion Cotillard (Two Days, One Night), Rosamund Pike (Gone Girl) and Felicity Jones (The Theory of Everything).
