Naomi WattsNaomi WattsHollywood is still mourning the loss of actor Heath Ledger.

And his ex-girlfriend, Naomi Watts, has cancelled her Sundance press.

The Brit born star, who grew up in Australia, dated Heath for two years.

Us Weekly reports she was set to promote her new film, Funny Games, at Sundance but following the sad news she has cancelled all press.

As such she won't be attending the movie's premiere, either.

She and Heath first met in 2002, while on the set of the movie Ned Kelly.
