Steve Tyler is to quit Aerosmith, according to his daughter Liv.The 'Lord of the Rings' actress is said to have told friends her lead singer dad is frustrated with the way the rest of the band treat him. A source told the New York Post newspaper: "Liv's dad is going to announce he's leaving Aerosmith soon because he can't take how the rest of the band behaves towards him. She said they don't appreciate him."However, a representative for the 59-year-old rocker denied the reports, saying: "Liv never said anything about her father leaving Aerosmith."Rumors of Steve's strained relationship with the band's guitarists Joe Perry and Brad Whitford have circulated for years.Tension between the trio resulted in Perry and Whitford quitting the group for five years back in 1979. Aerosmith are currently touring Europe and intend to release their fifteenth studio album in 2008. Liv, 29, only discovered Steve was her father at the age of nine when she noticed his daughter Mia Tyler looked just like her.
