Christina Aguilera was crippled with fears for her unborn child during her world tour earlier this year – she wore a carefully-hidden heart monitor in case of emergency.

The pop star admits she was terrified when she found out she was pregnant during the seven-month ‘Back to Basics’ tour, which ended in May, and would have quit if doctors hadn’t come up with an ingenious way of reducing the risks.

She says: “I was paranoid. There are so many things that could go wrong – somebody could slip, somebody could fall, I could fall. There was no way in hell I was going to jeopardise my baby for my show.

“I didn’t want to make the audience uncomfortable, like, ‘Pregnant lady onstage! Is she going to be okay?’ But I had to announce it to my band and my dancers, because I wanted to make sure they had my back.”

Aguilera is expecting her first child with husband Jordan Bratman early next year.

Christina Aguilera is the latest celeb to join the likes of Britney Spears, Lindsay Lohan, Paris Hilton – for leaving underwear at home while out partying. The 27 year-old star once criticised the trio for their lack of self-control while partying.

However, she was caught sans her underwear by paparazzi while enjoying a recent night out. Hopefully Christina will learn her lesson and not do a repeat performance.

Christina Aguilera has taken the title of her album ‘Stripped” quite literally by posing nude for PETA in Christmas e-card. The 27-year-old star wears just a pair of saucy gloves in the card, and tells shoppers not to buy fur this festive season.

“When I was 6 years old, I had a little fur coat, but that was it. That’s the only time I’ve ever had any in my life,” said Christina. She also proclaims herself as a hardcore vegetarian and also urges people to go for synthetic fur instead of real, thereby saving some money in the process. “When I became a vegetarian, I just started reading more and more about where fur comes from and what they do to the animals,” she says. “It all went hand-in-hand together. That was when I was 15.”

She adds: “They make really great synthetic fur – you really don’t need real fur. “And it’s cheaper, so why spend the money? The holidays are also a time when people freak out about their finances. “If you don’t want to spend the money, why not try some of the other options instead of killing a bunch of animals?”

Christina has now joined the likes of Alicia Silverstone, Pamela Anderson, Sophie Monk and Jamelia who have also posed nude for PETA.

Christina Aguilera says she’s expecting a baby, finally confirming what has become obvious over the past few months. The 26-year-old singer told Glamour’s U.K. edition that her plans for New Year’s Eve involve a new baby.

“That’ll be about the time I enter into mommyhood so I’m hoping to have started a beautiful family with my husband!” Aguilera is quoted as saying in a story posted on the magazine’s Web site. -mails to Aguilera’s representatives seeking comment weren’t immediately returned Monday.

Aguilera and music executive Jordan Bratman were married in 2005. “Oh, he’s thrilled! He’s just great,” Aguilera said of Bratman. “He’s so supportive and amazing through everything. He came with me on the last leg of the tour and he was my support system. … I’m a lucky girl.”

Aguilera, who recently wrapped up a world tour in support of her latest album, “Back to Basics,” plans to be a working mom. “I want it get it right, to balance (motherhood) well with my career,” she says.
