A close friend of Lisa has claimed to The Sydney Morning Herald on Saturday: 'She's lost 15kgs and is dating a nice man who is extremely kind, gentle and fun.'

'I've never seen her looking so good or sounding so good – she laughs now when she calls me,' friend Bryan Wiseman added, noting she's 'never been happier'.

Bryan, who has been life-long friends with Lisa, is an Australian actor who played Dr John Wilson on Australian drama Home and Away, between 1998 and 2003. 

He explained that he believes this time the split between the controversial pair is final, and that she's back to the old Lisa he used to know.
