Cameron Diaz cut a radio interview short after a joke was made at her best friend Drew Barrymore’s expense.

Cameron Diaz Cuts Short Radio Interview

Diaz and her Sex Tape costar Jason Segel had an interview to promote the movie on Australia's KIIS 106.5’s Kyle & Jackie O Show. At one point, Jackie O noted that child actress Giselle Eisenberg, who plays the pair's daughter in Sex Tape, somewhat resembles Barrymore in her E.T. days.

"Aw, yeah!" Diaz agreed. "She does, now that you mention it. And she's as bright and lively as Drew is, as well. She's a sweet little girl."

Sandilands then interjected, “Let's hope she misses out on the Drew Barrymore drug years, because those were a great thing to watch, but not so good to be in, I'd imagine.”

An irritated Diaz, who is close pals with Barrymore, replied, "I'm sure, Kyle, you've never been through a drug phase, have you? Or alcoholism or anything like that? Pretty clean; always did it right? Congratulations."

Sandilands then made an ill-advised transition to Diaz’s relationship with former Good Charlotte singer Benji Madden. When Diaz didn’t reply, Jackie O tried to steer the conversation to Segel and his weight loss for his role in Sex Tape. After Segel answered, Diaz had enough with the interview and put a stop to it.

"We're having to go now," she said. "Sorry, they're wrapping us up."

Jackie O, after saying goodbye to Diaz and Segel, was quick to point out Sandiland’s poor choice of questions. "Well, that started very well and ended poorly, I think. Good one, Kyle. You ruined that interview. Sorry to be blunt,” she said. “You brought up Drew Barrymore, her best friend's drug addiction in the past… She's her best friend. And then you brought up Benji. We all know how protective Cameron is about her private life."

Sex Tape is currently in wide release.
