Allison Williams' Red Carpet Beauty Ritual

Allison Williams enjoys oxygen facials before red carpet events.

The 'Girls' star has revealed the luxury beauty treatment, exercise and a fresh manicure and pedicure forms part of her ''ideal ritual'' before heading to A-list gatherings.

She said: ''My ideal ritual is to wake up, eat a little breakfast, exercise, shower, have a manicure/pedicure, have an oxygen treatment, eat lunch, go into hair and makeup, get in the car and go.''

Allison - who recently touched down in Los Angeles ahead of the Golden Globe awards on Sunday (11.01.15) - also listens to pop music to calm her nerves and makes sure she arrives on time.

She said: ''I like listening to pop music in the car on the way there. I hate being late, so I'm always trying to leave early.''

While the brunette beauty is yet to decide what she will wear to the star-studded event held at the Beverly Hilton Hotel, she has planned out the contents of her clutch which will include a snack and Mophie mobile phone battery pack.

When asked what will take pride of place in her bag, she said: ''A snack, gum and mints, chapstick, pressed powder, my ID, my room key, and a Mophie because my phone always dies. I'm still undecided about what I'm wearing.''
