According to the Globe's bombshell report, the two have bonded over their growing legal troubles.
Lisa Marie, 50, is suing Barry Siegel, contending he lost the $100 million trust left to her by her father, Elvis Presley.
Meanwhile, 55-year-old Johnny's suing his former business managers, who claim his shrinking movie fortune is due to out-of-control spending.
Another source told the publication, 'Johnny and Lisa Marie are working through their troubles together.'
'They're giving each other advice and bonding over their love of music.'
Neither Johnny or Lisa Marie have responded to the Globe's report.
