Katie Price is "glad" Jane Pountney's life is "ruined".
The former glamour model was left devastated last year when her husband Kieran Hayler - who has been treated for sex addiction - cheated on her with her best friend and she is pleased her former pal is now getting divorced from husband Derrick because she blames her for the infidelity.
She said: "I know Derrick and Jane are divorcing. Whatever she did I will never forgive her, and I'm just so glad her life is ruined.
"It's weird, Derrick and I have never been angry at Kieran, it's more Jane we're shocked by. I think because she'd dramatically changed.
"I suppose we didn't know Kieran as well as Jane - I married him after five weeks. But we'd known Jane for 20 years.
"I think that's why there's more bad taste about Jane. And she hasn't got an illness like Kieran."
Derrick has remained close to Katie - who has children Harvey, 12, Junior, nine, and Princess, seven, from previous relationships, and Jett, 19 months and Bunny, six months, with Kieran - and even joined her family in cheering her on when she recently competed on UK TV show 'Celebrity Big Brother', which she subsequently won.
She told Britain's OK! magazine: "The weird thing is, Derrick actually watched the 'CBB' final at my dad's house with my mum and dad, and they were all voting for me to win.
"Derrick will always be close to all of us. I haven't seen him since it all happened, but we will."
