SINCE that famous jungle shower in I’m a Celebrity . . . Get Me Out Of Here, Myleene Klass has become a household name. Three months after looking fabulous in that white bikini, she announced to the world that she was to become a mum and her world changed in an instant.

“If I met my old self I wouldn’t recognise her,” she laughs. “Everything changes once you have this baby that you would live and die for.”

Today the yummy mummy has a work schedule that would send most of us into a spin.

Last month it was trips to LA, Barbados and Berlin — not to mention squeezing in her Classic FM radio show, ITV’s Pop Star to Opera Star and designing her Baby K range of clothes and accessories for Mothercare.

“I have never been as organised as I am now but I have to know what I am doing every single day. I can’t just wing it or drop everything and go to the cinema.”

Wherever possible, daughter Ava (two and a half) gets to go to work with Mummy. “When she was really little I would sit her on my lap and she would read a book or paint but now she can run around so she can come on different jobs.” Myleene got by without any childcare for nearly a year. “I did it alone for nine months. I can’t do it alone any more and now Nanny Alex comes with us. You need to take help in any way you can and when we are home my mum is an absolute dream.”

Every little girl loves to dress up and Ava gets to do it with designer clothes on tap.

“She loves Mamma’s job because she gets to see all the jewellery and shoes laid out and she gets a whole dressing room to play with,” Myleene giggles. In fact, Ava is Myleene’s muse for her Baby K range of clothes for trendy tots. “When Ava was born I struggled so much to get nice clothes for her. I couldn’t understand why, just because they are little, they have to be dressed as clowns.

“Why would you ever wear anything with a giant giraffe or ABC written on it!”

Myleene has thrown out the rule book and introduced the colour black into her kids’ range. “Thankfully Mothercare didn’t dismiss the idea and I made black work but I didn’t do it in a sombre fashion.

“That was never the idea — it was to make kids’ clothes stylish.”

And where Myleene leads, others have followed. “Now the rest of the high street and certain designers are copying the range, which shows that little Myleene Klass is getting something right!”

The children of Gary Barlow and Emma Bunton have been spotted wearing Baby K designs but the real seal of approval came when Myleene flicked through a magazine and saw Elvis Presley’s grandchildren wearing the Baby K range. “I couldn’t believe it. My mum is the biggest Elvis fan in the world and there are his grandchildren in my outfit,” she says, shaking her head incredulously.

While Myleene is just putting the finishing touches to a range of Baby K leopard-print pushchairs, bedding and classical music toys, due in store in the next few weeks, her bags are packed for her latest M&S shoot. “I am not allowed to say where it is but I am very happy about it. Ava is going to come as well and we will have a mini holiday while we are there.”

Myleene is no longer fazed about working alongside supermodels. “I’m only 5 ft 5 in and when you first walk on set a part of you is thinking, ‘gosh, why am I here?’.

“But I realise that I am not a 6 ft 5 in goddess with long limbs. Instead I represent the normal mummy. In fact, I remember when Ava was first born and I was on a set and in between shoots I was breast-feeding her.”

Myleene met her husband Graham 10 years ago when she was singing in the band Hear’Say. Although his job involves travel, it doesn’t bother Myleene. “We see each other a lot more than people think but you’ve got to remember that I met Graham on tour so it isn’t a sudden shock that we don’t see each other every day.”

There is no denying that the couple are still madly in love. “I think we know each other well enough not to have to send expensive flowers because our love is real. We are surrounded at the moment by people having affairs and going off and being deceitful and if Graham did that to me it would break my heart. I love that man so much,” she says fiercely.

“He is the father of my daughter but first and foremost he is the man that I chose and I love him to pieces and flowers aren’t going to change that.”

It may be all glamour on photo shoots but, just like all mums, Myleene gets her share of sleepless nights. “It took two years but Ava is in her own bed finally.

“Now I give her a kiss and tell her that Mamma has got magic ears and I can hear everything. I tell her ‘just say “Mamma” and I will be there in a second’.

“Obviously the magic ears are the monitor and now every night I give her a kiss and she whispers ‘magic ears’, which is so sweet.”

Those ‘magic ears’ have been very busy lately as Ava has started having nightmares about monsters. “It’s horrible,” says Myleene, “but I told her that she has a magic wand and all she does is wave it, say ‘go away monsters’ and the monsters go away.

“It seems to be working but the whole magic wand thing bit me in the bum the other day when we spent some time on the Harry Potter set when a friend invited us.

“Emma Watson (Hermione) ran up to Ava and asked if she’d like to play with her magic wand before she did her next take, then Ava would not give it back.

“The prop woman came over, the director came over and filming was on hold until Ava eventually handed it back.” You wouldn’t know it from her sunny disposition, shiny locks and flawless skin but Myleene says she is always tired now. “Before Ava I used to think I was tired,” she laughs. “Everyone around me is so patient now because I’m so tired I’ve got no recall any more. The brain is gone!”

So how will Myleene be celebrating Mother’s Day next week?

“We will be going to my mum’s and Ava and I will pick her some daffodils. It has become a tradition in my family, ever since my brother got into trouble as a kid after picking all the daffodils for my mum from our local church’s garden.”

After living out of a suitcase, Myleene is looking forward to a day at home with Graham and Ava. “We have just moved house so we’re building things together for the new place. I just like doing normal stuff. I am not high maintenance whatsoever.”

So it may be on a beach one day and whisking Ava to a party the next. “I nearly ran myself into the ground last weekend making sure I could take Ava to her friend’s party in a church hall so they could run around and throw balloons at each other.

“I don’t know what people expect me to do with my time but I try to keep it as normal as possible because I want to have a grounded daughter. I just muddle along and at the end of the day I think ‘my gosh. I’ve got away with it again’.”
