Now back home in the US, the Dukes Of Hazzard star - recently dubbed 'sexual napalm' by ex-boyfriend John Mayer - says she's better equipped to handle criticism.

'I think that going on this trip, all these places, I really just found an inner peace. I found something within myself that I didn't know was there.'
