The 29-year-old - who is now five months pregnant - also revealed that her hormones are all over the place, reports the Daily Mirror.

"I’m thinking about names but I’m so hormonal, I keep going, ’Let’s call her Mango, that’s brilliant’," she’s quoted as saying.

"We’ve been talking to the baby and saying, ’Do you like such and such?’, and she will kick if she hates it. Some names have gone right out the window."

The pretty brunette is working throughout her pregnancy, including her job interviewing celebrities on the Screening Room for CNN.

"Robert De Niro gave the baby a rub," she grinned. "I also interviewed Johnny Depp. It’s funny now I’m pregnant my opinions have completely changed. Before I wanted him to have my babies, now I’m like, ’Oh, he’s a dad, isn’t he?’, and I want to know about his babies."

Myleene’s baby worries - April 18 2007
Pregnant Myleene Klass is reportedly worried that she is going to have an enormous baby.

The star, who is four months pregnant, is concerned after realising she had ballooned three dress sizes in just a few weeks - and she thinks the baby may follow in the footsteps of her Irish fiance Graham Quinn.

"I’m definitely in trouble," she told Closer magazine. "Gray was a big baby, so it’s obviously getting its size from him.

"People can’t believe I am showing so soon. We’ve had a history of small babies in our family but this one’s huge already."

The 29-year-old says she’s been having non-stop cravings. "I’m having major cravings," she said. "I’m eating loads of cookies and chips.

"I haven’t felt the baby kick yet, but I’ve been feeling very nauseous and had one episode of morning sickness in front of a police van which wasn’t my most glamorous moment."

Myleene, who has just started modelling for Marks And Spencer, added: "It’s like the ultimate present - I’m so happy about it."

Pregnant Myleene shows off bump - April 6 2007
A smiling Myleene Klass showed off her bump during a photoshoot.

The 28-year-old musician and TV personality posed in a red chiffon dress to publicise the new Marks & Spencer campaign.

She is expecting her first child with fiance Graham Quinn who was a bodyguard for the band Hear’Say in which she shot to fame.

The M&S television commercials were filmed before Myleene publicly confirmed her pregnancy.

She stars in them alongside Erin O’Connor, Lizzy Jagger, Twiggy and Laura Bailey.

Commenting on the new campaign, Myleene said: "Working with the other girls was like your first day at school. At first I was a little bit nervous. Who wouldn’t be standing next to Twiggy and Erin."

An M&S spokesman could not say whether Klass would model maternity wear for the chain.

The classically trained musician first hit the headlines as part of Hear’Say when the band won TV reality show Popstars in 2001.

More recently she appeared in the jungle game show I’m A Celebrity ... Get Me Out of Here!

During today’s photoshoot at an M&S store on London’s Oxford Street Klass wore an M&S Limited Collection dress which retails for £49.50.
