Olivia Wilde's fiancé Jason Sudeikis is a ''sneakerhead''.

The 30-year-old actress has revealed the 'We're The Millers' actor, with whom she has two-month-old son Otis, has a sports shoe collection to rival her own and his footwear takes pride of place in their bedroom.

She joked in the new issue of Oprah Winfrey's O magazine: ''Guests always expect me to have too many shoes. He's a sneakerhead with about 200 pairs of Air Jordans. They make up an extraordinarily colourful wall in our apartment.''

Olivia admits she is guilty of harbouring a fashion addiction of her own, so can't criticise him for his unnecessary purchases.

The 'Drinking Buddies' star added: ''If you were to peek inside my closet, you'd think I was a newscaster or a politician - I have dozens of blazers. I always buy them, thinking they'll pull together an outfit, but then never wear them.''

In the same interview, the new mother confessed she is also obsessed with collecting miniature objects.

She laughed: ''Miniature objects, anything tiny: furniture, cameras, trees - all of which you'll find scattered around my home. 'Honey, I Shrunk the Kids' is everything I could dream of in a film.''
