Reese Witherspoon is a living Red Carpet Barbie doll!

The Oscar winner looked stunning in a floor-length Zac Posen peony taffeta bustier gown, Fred Leighton jewels and Christian Louboutin heels at tonight's Golden Globes, while keeping her hair casual in lose beachy waves.

Fashion Police host Kelly Osbourne, who also donned a gown from the designer, couldn't help but Tweet, "Reese in @Zac_Posen is just breath taking!," after seeing the Water for Elephants star's gown.

Reese always gets it right!
