Christina Ricci has desperately wanted to dye her hair blonde for ''a really long time''.

The 37-year-old actress has revealed she has ''secretly'' wanted to ditch her brunette tresses for a lighter hue long before she took the plunge to die her hair, and trialled out a variety of wigs whilst filming 'Z: The Beginning of Everything' to ensure the hair colour would suit her.

Speaking to Net-A-Porter's The Edit magazine about her beauty overhaul, she said: ''I'd secretly wanted to go blonde for a really long time. I actually wear a lot of wigs in 'Z...', but I used it as an excuse.''

And the Californian star is ''shocked'' by how taken she was with her new do.

She explained: ''And I'm shocked by how much I love it. ''It's like the way little girls love sparkles - it's just such a pretty colour.''

Christina - who is known for playing the gothic role of Wednesday in 'The Addams Family' - has revealed she ''loves'' wearing garments that make her look like a ''lady'', and counts a ''tiny little Chanel suit'', which she accessorises with oversized jewellery and accessories, as her go-to ensemble.

She explained: ''I love looking like a 'lady'. There's nothing I like more than a tiny little Chanel suit and big jewellery.''

And the star - who has two-year-old son Freddie with her husband James Heerdegen - has admitted her outfit choices are always based around her petite five foot one inch frame.

She said: ''I'm 5 foot 1 inches so I'm obsessed with proportion - I really have to have a waist, or it has to be super-short.''

However, Christina avoids wearing short mini dresses or skirts because she has claimed she is ''too old'' for that style.

She said: ''And I am too old now to wear anything super-short without feeling ridiculous.''
