The secret to Jordan's svelte post-pregnancy figure has been revealed.

Just weeks after giving birth to baby Harvey, Jordan was spotted out and about looking as slim as ever.

Neil Trowse, an old friend and fitness manager of Dragons Health Club in St Helier's Avenue, Hove, said she has been a regular at the gym since the birth on May 27.

Jordan, who is an honorary member of the fitness club, has shed pounds using the gym but does not take part in any classes, preferring to use the exercise machines on her own.

Mr Trowse also confirmed that the glamour model was getting on well with Harvey's father, footballer Dwight Yorke.

He went for a meal in Brighton with the pair last week and said they seemed happy.

He said: "I've known Katie for ages - since she was about 14. We live near each other in Brighton.

"I went for a meal with her and Dwight last Tuesday. Contrary to what the papers are saying, they're not arguing. Dwight is taking an interest in the baby and they are happy.

"Harvey is very cute and very well behaved. She is lucky - he just sleeps most of the time.

"She has been to the gym a couple of times since the birth. She has been very active and got back into fitness."
