Nickelback (and Avril Lavigne) touch down in Australia for tour

22 November, 2012: Chad Kroeger and Avril Lavigne are rock music's odd couple but their generation gap romance is going strong, with Lavigne joining Nickelback on tour in Australia. 

The happy couple were spotted walking through Sydney airport together before Kroeger quickly got to business, performing a show in Melbourne. See photos of the pair - and the show here.

Perhaps Lavigne is tagging along to make sure that Kroeger keeps his rampant libido in check while he is on tour, as he recently revealed that she had confiscated his rolodex to prevent his contacting his previous conquests.

Speaking to Men's Health magazine this month, Kroeger said, "I don't think my libido has changed. I just think that my Rolodex has been confiscated. And I'm OK with that."

Kroeger went on to reveal that not even his fiancee listens to Nickelback - and claims this is a relief, as he doesn't want her hearing his 'racy' lyrics.

He added, "If a naughty Nickelback song came on, my fiancee would probably ask who it was. She'd be like, 'Who's this? This is good. I like it.'
