Katie Price has made no secret of her desire to transform her figure after claiming to have put on 1.5 stone over the last year.
And according an insider, Katie has been gushing about 'sexy, secret workouts' with her married personal trainer.
Last month Matt was seen putting Katie through her paces in a park in Surrey - which led to claims her jealous boyfriend Kris had banned them from the house.
The pair were snapped grappling together before Katie ended her session by stretching out into the downward dog move, under Matt's watchful eye.
A source close to the ex-glamour model told Heat magazine that's she's loving the one on one sessions.
"Katie has a genuine connection with Matt, who has been giving her a lot of self-confidence."
"Matt has made her feel sexy again and of course, he has a fantastic physique," they added.
Not surprisingly, Katie's admiration for the new man in her life is said to have riled boyfriend Kris Boyson.
Kris, also a personal trainer, has adopted a very different approach to helping Katie get trim.
The 30-year-old was seen showing his partner some tough love in reality series My Crazy Life - banning the mum-of-five's favourite sugary breakfast - white bread topped with marshmallow spread - and forcing her to eat in her underwear.
Katie told the cameras: "It's hardly surprising that I haven't got an confidence at the moment, when all Kieran did was cheat on me constantly for years. Kriis is supposed to be making me feel better about myself, but do you know what? He's not doing a very good job. In fact, he's failing miserably, because I feel more s*** than ever."
Katie Price's trainer says she's been to hell and back but has finally quit partying
In order to keep up working out with celebrity trainer Matt, Katie is reportedly meeting up with him in secret to avoid upsetting Kris.
"He cannot stand the idea of them working out together," said the insider.
As well as Katie Price , Matt has also worked with Love Island's Megan Bargon Hanson this year following her split from Wes Nelson .
Matt lives in Wiltshire with wife Monique Fiddes and their three children.
