The main actresses of the hit series supported the Time’s Up movement as they opted to wear black gowns for the annual ceremony.

Emilia, who plays Daenerys Targaryen in the HBO show, stunned in an elegant dress which fell to the floor.

The strapless garment featured a very low-cut neckline which allowed the British beauty to display her bare décolletage.

The 31-year-old showed off her newly-dyed blonde locks on the night and she completed the look by accessorising with a dazzling choker necklace.

Also making a rare appearance on the red carpet was Emilia’s on-screen enemy Lena who stars as Cersei Lannister in Game of Thrones.

Looking world’s away from the manipulative Queen of Westeros, the 44-year-old flaunted her slender frame in a chic frock which featured sheer fabric underneath her bust.

The Bermuda-born stunner styled her natural brunette locks in tousled waves and finished off the glamorous look with a gold ring and copper bangles.

The stars were joined by Kit Harington (plays Jon Snow) at the star-studded bash who looked extremely dapper in an all-back tux.

Gwendoline Christie (Brienne of Tarth) also followed the dress code in a stunning floor-length ruffled frock as she posed before heading inside the venue.

No doubt the actors will be feeling nervous on the night as Game of Thrones are nominated for Best Television Series at the Golden Globes.
