Axl Rose spotted leaving AC/DC's studio

Axl Rose, the frontman of Guns'N'Roses has been photographed leaving a rehearsal studio with AC/DC.
 
The rumour mill has been swirling for a while that Axl would be joining the band after Brian Johnson was sidelined.
 
Nothing has been confirmed by anyone but with Johnson suffering from a serious hearing problem that meant tour dates were postponed and could be rescheduled with a guest singer, the rumours started up.
