Liv Tyler's dad embarrassment

Liv Tyler hates it when her rock star dad wears trousers that are too tight. The 'Incredible Hulk' actress - who has a three-year-old son with her estranged musician husband Royston Langdon - is always embarrassed when Aerosmith frontman Steven Tyler dons his famous skin-tight pants.

She said: "I love my dad, although I'm definitely critical of him sometimes - like when his pants are too tight!" Liv, 30, also revealed the best relationship advice she has ever been given was from her model-and-singer mother Bebe Buell.

She added to Britain's Cosmopolitan magazine: "My mom gave me some great advice about men. She said, 'Watch out - they can be unreliable. But they can also be wonderful.' She had a bad reputation, which was unfair. Every time she happened to be seen with a man, she was supposed to be having an affair. "I see her described as a 'rock groupie' and I know she was never that. As a child, I watched her suffering so much and I decided then that I didn't want to go through that."

As well as romancing Aerosmith singer Steven, Bebe Buell dated and bedded many famous rock stars in the 70s, including Rolling Stones frontman Sir Mick Jagger, Iggy Pop, David Bowie and Elvis Costello. She conceived Liv with Steven while she was in a long-term relationship with American rocker Todd Rundgren. Bebe didn't tell Liv, who was born in 1977, that her real father was Steven until the late 80s.
