Nicole Kidman, What HAS Happened To Your Hair?

Erm, what has happened to Nicole Kidman's usually glamorous (reddish) blonde curls?

The actress has ditched her famous tresses in favour of a brown bob which is making her look dowdy in the extreme.

Thank goodness, then, it's just for a film. Phew! You had us worried there for a minute, Nic.

The actress is currently shooting The Family Fang in upstate New York - and we're guessing she plays the part of a put-upon housewife.

The Family Fang is a bestselling novel written by Kevin Wilson, and actually tells the story of a brother and sister who return to their family home in search of their world famous parents who have disappeared.

It also stars Christopher Walken, and Jason Bateman, who's actually directing the film, too.

Nic also rocks some rather unappealing clothes on set, working a drab blue V-neck tee, khaki trousers and black trainers. She's obviously suffering for her art.

Just to give us a sense of normality, here's a pic of Nicole as she usually looks on the red carpet recently.

Better, right?

As for Nicole's next project, according to Just Jared it was recently announced that Nicole and Reese Witherspoon will partner up to option the screen rights to Liane Moriarty's Big Little Lies, which centres on "a group of Australian mothers whose kids all go to the same kindergarten. A mishap with a broken heel leads the "mums" through a series of events that eventually ends in murder.
