Davina's voice has been voted one of the UK's best, according to a Radio Times poll of nearly 5000 people.

Users of the magazine's website were asked to choose the nicest tones from 50 of the most distinctive voices in TV and radio.

On the female list, actress Joanna Lumley topped the chart, followed by Mariella Frostrup. Our Davina came third, ahead of newcasters Fiona Bruce and Kirsty Young.

Jo Whiley, Kate Thornton, Lorraine Kelly, Moira Stuart and Sue Lawley completed the Top 10.

Davina today bacome the latest star to have a waxwork carved in her likeness, as her double was unveiled at Madame Tussaud's.

The interactive model - which cost £100,000 to make - allows fans to become Big Brother housemates living in the famous house.

Visitors will get the chance to be interviewed by Davina and enter a replica Diary Room where they can share an intimate encounter with Big Brother.

When confronted with the waxwork, she exclaimed: "Oh my God! It's quite weird, isn't it!" adding: "I think it's brilliant, it's even got my funny hand."

The interactive model has a number of sayings, including an adaptation of her famous catchprase: "Big Brother housemates, you are live at Madame Tussaud's. Please do not swear."

Davina has also recorded soundbites for her figure such as: "Congratulations, you were a brilliant Big Brother housemate" and "I was watching you in the Diary Room, you were so funny."

A spokeswoman for Madame Tussaud's said: "The Big Brother Experience will give guests a once-in-a-lifetime chance to converse with Big Brother live while sitting on the famous diary room chair.

"They will get a taste of what it's like to exit the house when they are then invited onto the Big Brother stage to meet the bubbly presenter Davina McCall."

Davina's model is wearing an original black dress which she wore for the Big Brother 5 finale.

Meanwhile, when questioned by reporters about her rumoured pregnancy, she simply uttered "no comment", although kids were obviously on her mind when she made a beeline for a child who was at the attraction, saying: "Is that someone`s kid? He`s gorgeous."

Reports in today's papers suggest that Davina is expecting her third child.

She was apparently overheard chatting to friends about her bulging tummy despite now having her new BBC chat show.

She was overheard saying: "We're having another baby and we're absolutely delighted.

"I'm so looking forward to having another baby. We are over the moon."

Davina already has two children with her hubby Matthew Robertson; Holly, 4 and Tilly, 2.

She recentley confessed that she'd been longing to give her husband a boy after having had two daughters.

However, fans of Big Brother have predicted Davina will miss out on presenting the new series this summer, as her suspected due date clashes with the final weeks.

She presented both Big Brother 2 and Big Brother 4 whilst heavily pregnant, giving birth on both occasions just two months after the finale.

Davina has said her wild past will help in her new role as a chat show queen.

She was almost killed by drug and alcohol addiction when she was younger, but then cleaned up her act.

She says her experiences will help when it comes to talking to troubled celebs, telling the Radio Times: "I've lived a lot, so I'll be able to say, `Been there, done that.'

"When I hear about friends who have relapsed and died, I'm very grateful to be around. Every day is borrowed time."

The first guests on "Davina" include Hotel Babylon actor Max Beesley, along with showbiz couple Tess Daly and Vernon Kay.

However, she denies claims she signed a £1m deal for the series. She said: "I have no contract. I'm just doing eight shows - I can't wait to get my teeth into it.

"I understand people will be gunning for me, and not everyone will like me. I'm doing all right, so I'm easy to knock.

"My grandmother tries to get me to do something more gritty than a chat show, but it's important to entertain people.

"Tony Blair probably doesn't want to watch Paxman or Andrew Marr. He'd prefer to kick off his shoes and see me."
