Benji Madden has dodged questions about his rumoured romance with actress Cameron Diaz.
Madden has been photographed spending time with Diaz in California in recent weeks, fuelling reports they're dating.
However when asked about the reports on Kiis 1065's Kyle and Jacki O Show on Monday Madden was very reluctant to talk about his personal life.
"Apparently Nicole's been matching you up with Cameron Diaz, what's happening there?" Kyle asked.
After a few um's and ahs, Madden responded: "Oh Kyle and Jacki O, you know what, I'll talk about it when I see you next week."
"I can always count on you Kyle," Madden added.
The rocker had reportedly been introduced to Diaz by his sister-in-law, Nicole Richie.
Madden and his twin brother Joel from band Good Charlotte were on the Sydney radio show to talk about their new music venture. The duo have just released their first single under The Madden Brothers.
We Are Done features on The Maden Brothers' first album to be released later this year.
