The Entourage star appears alongside Cyrus and Kelly Osbourne in the film, and he admits even he was surprised at just how well he got along with the 18-year-old Hannah Montana singer/actress.
He tells Eonline.com, “I think I must be an 18-year-old girl because we got along really well. It was just so much fun. I had so much fun with her and we had great chemistry. I was really, really weird – we’re like polar opposites.”
And Piven has defended Cyrus against criticism for being a bad role model to her young fans, after she came under fire in December (10) when film footage of her smoking a huge pipe, believed to contain the legal high Salvia, was posted online.
The 45-year-old actor insists Cyrus is behaving just like any other teen her age.
He says, “You know, you can judge her, but what were you doing when you were 18? She’s kind of amazing. There’s something so incredibly refreshing about someone who is exactly who they are. There’s nothing pretentious about her. She’s this force. She loves to laugh.”
The new pals demonstrated their friendship during a wrap party for So Undercover earlier this week (begs24Jan11), when Cyrus took to the microphone with Piven on drums for an impromptu performance of I Love Rock ‘n’ Roll.
