A Hollywood love story!

Naomi Watts opened up about her first meeting with beau Liev Schreiber, 43, in the October issue of More.

"I was wearing Calvin Klein, a very flirty, feminine dress," the Dream House actress, 42, says of the chance encounter at the Metropolitan Museum of Art's annual costume ball in 2005.

After the pair -- who now have two children, Sasha, 4 and Kai, 2, -- exchanged numbers, the budding romance continued to heat up while Watts was living in L.A. "We spoke on the phone for several weeks and emailed," says Watts. "And then I made up some excuse to come to New York and the rest is history."

This isn't the first time Watts has talked about that fateful night. "We were both single and we were both very aware of each other in the room. I don't know about love at first sight, but there was a strong desire for one another," she has said.
