Discovered: Daughter of Steven Tyler of the band Aerosmith and Bebe Buell, former model and Playboy Playmate of the Month, Liv got started at age 14 as a model. A year was enough of the modeling grind, and she decided to become an actress. She was offered the part of Callie in the 1995 movie Heavy and only three weeks later was cast in the film Silent Fall.

Resume: By age 20, Liv had already starred in several successful movies, including Stealing Beauty, That Thing You Do! and Inventing the Abbotts.

The role that made her a huge star was the blockbuster 1998 film Armageddon, alongside Ben Affleck.

She proved her sophisticated acting skill with a role in Onegin - based on the 19th century Russian novel Eugene Onegin by Alexander Pushkin - where she convincingly portrayed the character of Tatyana Larina.

More recently she starred in The Lord of the Rings series as Arwen Undómiel.

In 2004, Liv again starred opposite Ben Affleck in the romantic comedy Jersey Girl. She is currently working on several films including Lonesome Jim, August Rush, and Coin Locker Babies.

Quotes: "I have these slumber parties with my father and when we can't sleep we stay up all night trading beauty tips. He knows all about the good creams and masks," - Liv Tyler.

"It wasn't until I came back home after such a long time away that I realized how much hype there was about this. I get to play someone 3,000 years old. I'm 23, so that's quite an acting challenge," - Liv Tyler on playing Arwen in "Lord of the Rings".

"I've been told that if I'd lose weight I'd have more work, but I refuse to submit myself to those standards. To the rest of the world, I'm slim, and I like the way I am," - Liv Tyler.

"When I did Stealing Beauty I was just a kid. I'd done a couple of movies, but I'd never been to an acting class in my life. But what I took away from it more than anything was the sense that, even though I was the central character, it was my job to get completely lost in the film. I had a real awareness of Bernardo Bertolucci as a filmmaker, not just a director, painting a canvas in which I was just one element," - Liv Tyler.

Trivia: Liv's mother named her after Liv Ullmann because she was on the cover of TV Guide the week Liv was born.
