Liv Tyler Gets "Irresistible"

Liv Tyler, best known as the elf queen Arwen in "The Lord of the Rings" series, has a new role as the "Very Irresistible" face of a new Givenchy fragrance.

After taking two years off to spend time with her husband, musician Royston Langdon, and their son Milo, born in 2004, Tyler also is set to appear in a string of new films-including an upcoming movie remake of "The Incredible Hulk."

In that movie, Tyler plays the one true love of the "Hulk," but it wasn't a dress-up role. "I literally wear the same shirt and jeans for pretty much the whole movie," she said, "so it's so wonderful to get to go and do a shoot for a day and wear beautiful clothes and have your hair and make-up done."

The shoot for "Very Irresistible Givenchy" sounds a bit easier than shooting a stunt-filled action movie. "We were in L.A. and they had this idea of me (being) very free -- me laughing and smiling and jumping on a bed," Tyler says, "so I basically jumped on a bed for five hours straight listening to The White Stripes."

Liv Tyler made an appearance in a Sephora store in Times Square to sign autographs for the first purchasers of the new perfume.
