Actress Naomi Watts' is now a part of New York City's Empire State Building, after etching her name at the top of the colossal structure.

Watts and film-maker Peter Jackson went to scout out the Manhattan landmark as preparation for their anticipated King Kong remake, and the screen beauty took the opportunity to leave her personal stamp behind.

She says, "(We went) pretty much to the top, certainly further than the public can go. The spike, I didn't go up there, but the last tier, there's a wall only about four or five feet high and I went to there and it was very windy. It was very scary."
