The 34-year-old model - who was married to the cage-fighter for a year until early 2011 - has been talking with the blonde reality TV star following revelations Alex is a cross-dresser who set up a sex dungeon in their home.

Speaking at the launch of her jewellery collection, she said: "I`ve actually been in contact with her behind closed doors and we`re discussing our own little things."

Katie - who recently split from Argentinean model Leandro Penna - also reveals she has seen pictures of the supposed "dungeon" previously.

She added: "I`ve seen the videos and pictures yeah. I`ve seen more than you can imagine."

She plans to reveal details of the relationship she had with him herself when she releases a tell-all book next year.

Katie told the Daily Mirror newspaper: "Like I say it goes back to the Gareth Gates days, everyone was saying, `Oh she wishes she was seeing him` and then it was true. I said things about Alex, not into detail, but it was true.

"You always know I don`t lie. I know the truth. Lucky I`m doing my book next year because boy, there`s a lot going in that one!"
