Avril Lavigne hasn't moved on as quickly as some media reports have made out.

It has been claimed the 'Girlfriend' punker had already got herself a new boyfriend, less than a month after she split from husband Deryck Whibley.

The Sum 41 rocker was seen holding hands with a unnamed female, and reports soon suggested Avril had also found new love in the form of billionaire Justin Murdock. But Lavigne's rep tells GossipCop that the stories are "totally 100 per cent not true."
