The former glamour model - who is six months pregnant with her fifth child - is struggling to cope in the wake of discovering her husband has been having a ''full blown sexual affair'' with her married best friend, Jane Pountney, for the last seven months and is seeking spiritual guidance to help decide whether she should end their marriage for good.
The 35-year-old star's mother Amy has also been pushing her to consult a medium, despite one advising her to marry Kieran last year, leading her to tie the knot with the part-time stripper after a whirlwind romance.
A friend of Katie's told The Sun newspaper: ''She's a big believer in psychics and Amy wants her to feel it'll be OK in the end. Things are so awful, she needs spiritual guidance. She wants to ask about the consequences of a divorce.
''It's hard for her, especially as she's worried about her pregnancy, but this might give her hope.''
Katie previously admitted she had wed Kieran because a psychic told her the man of her dreams would be called Kelvin, and she decided his name was ''close'' enough.
However, the pal insists the mother-of-four isn't taking things likely and she is desperate to make the right decision for the sake of her children, Harvey, 11, Junior, eight, and Princess Tiaamii, six, from previous relationships, as well as nine-month-old baby Jett, her son with Kieran.
The source added: ''It's no laughing matter for her. She's desperate for answers. She thinks they're scheming to get their stories straight. And she says Jane would have liked flings with several of her exes - but only Kieran was stupid enough to fall for it.''
It's time for a riot grrrl revolution.
