She and her showbiz pal Jordan – real name Katie Price - were once notorious party girls, renowned for attending showbiz bashes and hitting London’s top nightspots.
But Michelle Heaton insists the pair have both matured over the years and says family life has definitely tamed their wild party ways. Michelle has three-year old daughter Faith and 17-month old son AJ with husband Hugh Hanley whilst Jordan has 13-year old Harvey from a past romance with Dwight Yorke, Junior, ten, and Princess, eight, from her previous marriage to Peter Andre and Jett, 23-months, and Bunni, one, with current husband Kieran Hayler.
She laughs: “Katie and I have both changed our party ways. We saw each other at a party in London last month and she got the last train home, whilst I was tucked up by 11. We're such grown ups now!”
The singer turned personal trainer has most definitely overhauled her lifestyle after developing a passion for fitness in 2009. The once size 14 star now boasts a toned size 8 body and credits regular workouts and a clean eating diet for her hard earned results.
She says: “I wake up at 5am and when Hugh is getting the kids their breakfast, I run to our local gym for a workout. Then he leaves for work and I’m on mummy duty for the rest of the day. It’s difficult but I fit my exercise in. My friends come to me for advice on fitness and diet, which is a change from my younger years when they’d ask me where to go to get drunk!”
Michelle opened up in 2011 about her obsession with staying slim during her time in popband Liberty X, revealing an addiction to diet pills had left her with unexplained arrhythmia.
And Michelle – who turned 36 last month – says despite her healthy lifestyle, she understands the importance of balance with her diet.
She says: “I've had a few weeks off my diet recently for my birthday but I don't beat myself up. When I was younger, I used to get so panicked if I fell off the wagon because I didn't realise I was strong enough to lose it again and it was no big deal.”
Michelle re-joined her Liberty X bandmates in 2013 for ITV's the Big Reunion and formed a friendship with Atomic Kitten's Kerry Katona - with the girls bonding over their joint pregnancies at the time.
Kerry has endured a rocky time with husband George Kay recently, sparking speculation they may have split last month.
Michelle says: "I've reached out to Kerry to see if she's ok since the George drama. I haven't heard anything back but obviously I wish her all the best. She's a tough cookie!"
Michelle Heaton is working with leading toy manufacturer HTI to launch the Mamas & Papas Armadillo Dolls Pushchair, which allows children to enjoy hours of fun, pretending to be just like their parents. It’s available from Argos.
