Cameron Diaz hangs up on Kyle Sandilands after awkward interview: 'We're having to go now'

Kyle Sandilands has done it again... and co-host Jackie O doesn't have his back this time.

The KIIS FM radio duo interviewed Cameron Diaz and Jason Segel promoting their new film Sex Tape, but the interview skidded off the tracks when Kyle got too personal with Cameron.

The shock-jock brought up Cameron's pal Drew Barrymore's "drug years" and dropped a reference to Cameron's new boyfriend Benji Madden... resulting in a super-awkward exchange that ended with Cameron abruptly wrapping the interview. Listen above!

Jackie O gave Kyle a lashing afterwards: "You ruined that interview, sorry to be blunt. You brought up Drew Barrymore, her best friend's drug addiction in the past. And then you brought up Benji and we all know how protective Cameron is about her private life. So the two things that probably would get her off-side, you went there."

Kyle's response? "Maybe they should have just bought ads if they want to sell the movie, I want to find out other things."
