Rugby star Danny, 26, and former Celebrity Big Brother contestant Jasmine, 31, recently went public with their relationship, and Katie had a few things to say about it.

She blasted: "You hear the phrase two peas in a pod. That's exactly what I thought when I saw my ex Danny Chipolata – sorry, Cipriani – hanging around with Jasmine Waltz. They really do suit each other."
Katie and Danny were together in 2011, but Katie revealed in her latest autobiography that she walked on him with another woman.
Continuing her rant in her British magazine column, Katie said that Jasmine is just as bad as Danny, after she hooked up with Lee Ryan on CBB and sold a story implying he is gay after their split.

Katie said: "I wouldn't trust her and I certainly wouldn't trust Danny. Jasmine's obviously come back to the UK to make some money, so watch this space.
"I can't wait to read her kiss and tell on Danny once he's done the dirty on her too."
Meanwhile Katie, who gave birth to her fifth child earlier this month, missed her Fubar Radio show today.
While no explanation was given for her absence, she mysteriously tweeted about a hospital visit this afternoon.
