Liv Tyler didn't know that Steven Tyler was her father until she was married.

Liv Tyler was 11 years old in August 1988 when she looked up at a poster of Steven Tyler on her bedroom wall and realized that it would change her life.She said in 1997 that she thinks Steven is her father.After confronting her mother, she realized that her suspicion was correct.

Liv believed that she was the daughter of Utopia singer Todd Rundgren.The birth of their daughter in New York City in July of 1976 was the result of a brief fling between Steven and the Miss November 1974 Playboy Playmate.Rundgren signed her birth certificate, gave her his last name and raised her as his own even though he knew he wasn't her father.

Steven was reported to have a drug addiction at the time that led to the decision to keep the paternity a secret from Liv.She said that she and Rundgren made a pact that if it ever became an issue, they would tell Liv at 18.

Liv knew her father's identity long before that.She first met Steven at a Rundgren concert when she was 8 or 9 years old and remembers him buying her a Shirley Temple at the bar.The actress says she fell in love with him despite having no idea who he was.

Liv said it must be chemical.When I met him as a little girl, I didn't know why, but I figured it out quickly.

She has a striking resemblance to him and his daughter Mia Tyler, who was born just more than a year after her.Liv said she was like looking at her twin when she saw her standing at the side of the stage.

She changed her name from Rundgren to Tyler after discovering the truth.When she was in high school, Liv appeared in a music video with a friend, and they collaborated again in 1998 when Steven's band contributed a song to her movie, Armageddon.

Even though he and Rundgren split, he remained involved in Liv's life.She explained that she grew up with a nice mix of parental figures, as well as with her aunt, uncle, and cousins in Maine.

She considers Rundgren and the singer to be her fathers.Todd chose to be a father figure to me.She has said that she would visit Rundgren at Woodstock in the 80's if she could.He was a loving force in my life even though he and my mom weren't together.

Liv doesn't mind that Buell kept the secret from her.She shared in 2015 that it was an emotional story.When my mother had me, there was a bit of confusion about where I came from, but I was well taken care of by my family, which was wonderful.

The "Stealing Beauty" premiere was held in Los Angeles, California on September 7, 1996.

Steven has been involved in the lives of Liv's children: Milo, Sailor, and Lula, with British sports agent Dave Gardner.Steven, along with her sister Mia, were present when Sailor was born six weeks early in 2015.She said that she never expected to have a baby with her sister and dad.I called Mia and she showed up at the hospital.He cut his cord before Sailor was born.It was crazy.

She said Steven is fun for all the grandparents to get to play with because he is very sweet.He makes weird noises with his mouth and animal noises.He is very playful and funny, he has things in his hair and jewelry, and he is just very fun.
