Watch below: House of the Dragon star Milly Alcock appears to be drunk at the Golden Globes.
Alcock appeared on stage after the epic fantasy series won the award for Best TV Drama. Standing next to co-star Emma D'Arcy and director Miguel Sapochnik, Alcock seemed very tipsy as she leaned on D'Arcy.
As Sapochnik gave his speech, Alcock giggled throughout and at one point poked her finger at the audience before placing it on her lips.
Alcock made reference to the incident on her Instagram Stories, reposting a picture of her on stage along with the caption "Ummmmmm".

A number of viewers watching the ceremony found the funny side of Alcock's seemingly drunk appearance with one posting on social media: "Milly Alcock slightly drunk on Golden Globes holding Emma D'arcy with her life iconic."
In House of the Dragon, Alcock plays the younger version of Rhaenyra Targaryen with D'Arcy playing the character in adulthood.
Alcock has previously discussed filming some of the show's controversial scenes including a depiction of incest along with Matt Smith who plays her character's uncle.
Alcock said: “[We] were just kind of mates. So, it was quite comfortable. We had an intimacy coordinator, and we worked with her through the rehearsal process and blocked it out months before."
As well as House of the Dragon, Alcock is best known for her role in Sky Atlantic comedy series Upright alongside Tim Minchin.
Alcock has also starred in a number of projects in her native Australia including crime thriller Reckoning and supernatural series The Gloaming.
