Just when we thought that Katie and Peter had put all their issues behind them, the former glamour model has lodged new legal papers with the High Court.
Katie is seeking £250,000 in damages for "misuse of private information" which has caused her "serious distress".
The defendants named in the papers filed last week include Katie’s former manager Claire Powell, Peter and former friend Jamelah Asmar.
Katie is accusing her ex-manager of asking an employee to compile false smears about her private life, resulting in an email being written that alleged Katie was at the “point of having an affair” with riding instructor Andrew Gould.
It's thought that the same email contined private medical information about Katie, and Katie claims the alleged existence of the email is a breach of contract.
A statement from Katie's former management company Can says,
“We consider that the claim is without merit. The matter is in the hands of our lawyers and will be defended vigorously.”
This isn't the first time Katie and Peter have had legal dealings since their divorce three years ago. Let's hope it's the last.
It’s tough being Simon Cowell.
Particularly when the ratings for The X Factor in the UK continue to dwindle, and in the US The Voice has scheduled to go head-to-head with the first show in the new series of The X Factor US.
So, Simon has turned to his ex-fiancee Mezhgan Hussainy for a little bit of moral support - and possibly a cuddle.
Simon and Mezhgan both arrived together in Si’s flash Rolls-Royce Phantom at the Beverly Hills Hotel in LA to attend some X Factor promotion. It’s the first they’ve been seen in public together since splitting earlier this year.
“They’ve always been close and remain on good terms,” a pal tells The Sun.
Muse frontman Matt Bellamy has opened up about fatherhood, admitting that the birth of his son with actress Kate Hudson freaked him out.
“I don't understand why no-one had warned me about how horrible it would be,” he’s told German mag Gala.
“The baby's head was weirdly elongated when it came out. That freaked me out a bit,” he added.
Which pretty much sums up why women go through childbirth and not men – they are far too squeamish.
Matt has now settled into his role as a new dad, and loves being a parent,
“Being a father changes so much - the way you look at the world and yourself,” he says.
"There's nothing that's as much fun as a baby - it's endless joy. I'm really happy with everything."
