Daughter of Steven Tyler of the band Aerosmith and Bebe Buell, former model (and Playboy Playmate of the Month) and stalwart of the backstage rock scene of the 1970s, Liv grew up thinking that rock star Todd Rundgren was her father. But as she was growing up Tyler began dropping by to visit, and Liv noticed that his daughter Mia looked enough like her to be her twin. She confronted her mother, and was told the truth; by the time she was 12, she had taken her father's name. At 14, she and her mother left Portland, Maine, for New York, where she got her start 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 Heavy after a single reading, and only three weeks later was cast in Silent Fall; James Mangold, director of Heavy, decided to delay shooting until Liv was available. With seven films in the 1993-96 period, her career took off.



Liv's mother named her after Liv Ullmann because she was on the cover of TV Guide the week Liv was born. A cameo role in Everyone Says I Love You (1996), a musical directed by Woody Allen, was cut; Allen was impressed enough by her performance to write a personal letter explaining that her part was cut in editing. Armageddon (1998/I) opened on her 21st birthday. Aerosmith's video for "Crazy", in which Liv co-starred with Alicia Silverstone, was voted #23 in VH1's top 100 music videos of all time. Wears a size 10 shoe. Voted the 6th Sexiest Female Movie Star in the Australian Empire Magazine (September 2002). Didn't meet her father until 1988. Learned swordfighting for her role as Arwen in the The Lord of the Rings: The Fellowship of the Ring (2001). But the script was changed and she never got to use her skills. The decision to cast her in the video for "Crazy" was based on seeing her Pantene commercial, with absolutely no knowledge her father was in the band. Was born at 6:08 a.m. She is a spokesperson for Givenchy Perfume and Cosmetics. She got married in Barbados. Ex-sister-in-law of Dave Buckner. Her son Milo was born on the same day as the release of the Platinum Series Special Extended Edition of the Lord of the Rings Trilogy (December 14, 2004). On a TV documentary about the making of the "Lord of the Rings" movies, she said she really liked delivering her lines when they were in the fictional Elvish language. Used to be a vegetarian. Recorded a song for The Lord of the Rings: The Two Towers (2002), but because Peter Jackson didn't feel the song was right for the intended scene, he put it into the extended edition of The Lord of the Rings: The Return of the King (2003). Since then, Liv has stated how much she enjoyed singing and recording and how she has always felt a strong relationship towards music. Godmother of Marlon Richards's (Keith Richards's son) children. Is only eight years younger than Cate Blanchett, but plays her granddaughter in The Lord of the Rings. Friend of Orlando Bloom, Gwyneth Paltrow and Kate Moss. Ex-stepdaughter of Cyrinda Foxe.
