Eliza Doolittle is happy for ex-boyfriend Benji Madden and his new girlfriend Cameron Diaz.

The 'Big When I Was Little' hitmaker, who was in a relationship with the Good Charlotte rocker between 2011 and 2012, is still on good terms with the musician and is pleased he has found love with the Hollywood actress.

Asked if she knew about their blossoming relationship, Eliza exclusively told BANG Showbiz: ''I didn't know that, I don't Google for it.

''Benj is a friend, I only have positive vibes for him!''

The guitarist only stated dating the Hollywood actress a few weeks ago after being introduced to her via his twin brother Joel Madden's wife Nicole Richie, but he is reportedly already completely smitten with her.

Meanwhile, Eliza, 26, has also moved on and is now dating Jack Leslau, the son of property tycoon Nick Leslau.

Talking about her new beau, she said: ''[It's going] great. We've been loving for a little while now.''

Eliza, who is the face of Malibu's new Best Summer Ever campaign, insists she's learnt a lot about her past relationships and having her heart broken when she was younger.

She said: ''The thing I've learnt most since then though is to live and love in the moment. What will be will be. If it lasts for a lifetime then great and if it last for 10 years then great and if it lasts a few months then great. The only thing that holds true happiness is that moment when you're in it. Nothing can be controlled.''
