The `Super` actress revealed she loves to sing with her `Aerosmith` frontman father, and although he constantly tries to get her into the studio with him, her busy schedule has prevented them from collaborating properly.
She said: "We sing all the time together. We always talk about doing something together. Sometimes when he is in the studio he`ll say `come down and sing backup or sing with me on this song.` But I`m usually somewhere else, and our schedules make it so hard to meet up."
Although they have not managed to work together yet, Liv - who has a six-year-old son Milo with ex-husband Royston Langdon - revealed there are many bonuses to being a rock star`s daughter, including evading the law.
She explained to Fox411`s Pop Tarts: "It has been really interesting for me because my whole life, especially in America, people relate to and really love Aerosmith. I`ll be pulled over by a cop and they`ll say `Oh tell your dad if he ever needs a new guitar player like here`s my card`. People really love Aerosmith."
However, Liv admitted she is delighted her father took a role on the judging panel of `American Idol` this season as people can now see how "funny and sincere" he is rather than admire him for his rock star credentials.
She said: "I`m not particularly familiar with `American Idol` as a whole, I`ve seen it a couple of times, but I feel really happy for my dad that he`s doing something he loves and something different. Now I`m experiencing something so different. People are coming up to talk to me about my dad`s heart because they think he`s so funny and sincere. It`s really sweet because that`s the man that I`ve always known my whole life, but it`s interesting that the world gets to see that part of him now."
