Naomi Watts - Naomi Watts needs her wigs

Naomi Watts needs her wigs

Naomi Watts couldn't live without her wig collection.

The 43-year-old actress has accumulated a large number of fake hair pieces throughout her career in the film industry and claims they are by far her most valuable fashion accessories.

Naomi joked: ''If my bathroom cabinet was on fire, I'd make a beeline for my wig collection. Seriously. They're the only valuable things in there - some cost thousands. You never know when you might need one for a job.''

The Hollywood star also confessed her flawless complexion comes from regular Sarah Chapman facials - favoured by the likes of Keira Knightley, Scarlett Johansson and Kate Moss - and she relies on lots of beauty sleep and water to keep her skin hydrated.

Naomi - whose long-term partner is Liev Schreiber - explained that all her skin needs is: ''A Sarah Chapman facial. God, they're brilliant - all that massage and lymphatic drainage. I go into her little room, have a snooze, then walk out looking all shunt and fresh.''

She added to Tatler magazine: ''And water. As much sleep as I can get. And Jelly Aquarysta by Astalift. It has a weird, wobbly consistency but makes everything feel lovely and plump.''

However, the 'Diana' actress' exercise regime is much less strict and she gets most of her exercise at home, looking after her two sons.

She said: ''I keep fit mostly chasing after my two boys, Sasha, five and Kai, three. I do a bit of Pilates and the odd dance class too.''
