AceShowbiz - Steven Tyler once embarrassed his daughter Liv Tyler by hitting on her friend Cameron Diaz.

The Aerosmith rocker was forced to confess his secrets during an appearance on "The Late Late Show with James Corden" on Thursday night (May 17) when host James invited him to participate in a segment called "Spill Your Guts" or "Fill Your Guts".

Steven had to choose between eating disgusting food - including a cow's tongue and bird saliva - or answering a personal question.

One question James asked was whether or not the rock legend had ever hit on any of his daughter Liv's friends, to which he replied: "Yes, I have. And I got a lot of s**t for it too."

Steven then revealed he was once seated next to Cameron - who is now married to Benji Madden - and asked her out.

"Cameron, should you ever need someone to take you to the movies or you know, like, if I was to, you know, ask you to show me around London," he recalled of a conversation with the "Charlie's Angels" star, before explaining that an impressed Liv put an end to the chat by stating, "Daddy, you're hitting on my best girlfriend!"

"And I got ashamed for a moment," the rocker confessed.

Later in the tell-all interview, the 70-year-old admitted he had spent "about $2 million" on drugs in his lifetime, with most of the cash used to buy cocaine.

"I snorted half of Peru," he joked.

While Steven had no problem discussing his daughter and his drug problems, he wasn't prepared to insult his band members. And when it came to ranking the Aerosmith members in order of talent, or eating cow intestine, he reluctantly chose the latter.

Before taking a bite of the intestine, the star said: "I got to go on tour with these guys. It's bad enough the s**t I say to them."
