Kim and Kanye's $350 million baby!

We can expect the entertainment power couple’s bank account to rocket up to a massive $350 million – just for successfully making a bub.

Her every move is documented by her TV show and a flock of paparazzi, so quite how Kim Kardashian managed to keep her pregnancy news secret is anyone’s guess. But at a concert in the US last week, her boyfriend of eight months, rapper Kanye West, let the cat out of the bag.

With the words, “Make noise for my baby mama right there,” Kanye told fans the happy news – while Kim beamed in the audience. “It’s true! Kanye and I are expecting a baby,” she confirmed on her blog afterwards. “We feel so blessed and lucky.” “Kimye”, as Kim and Kanye have been dubbed, stand to make a pretty penny to add to their combined net worth of $150 million.

“Kim’s baby will take her brand to the next level – and give her a licence to print money,” Hollywood showbiz consultant James Desborough tells Woman’s Day. “Kim’s appeal is now so broad that she could make over $200m in the next 18 years. In just hours after the announcement, Kim was bombarded with $100m worth of endorsement offers asking for mum and child to be the faces of everything from prams and diapers [nappies] to car seats and baby food, and that is growing by the day.”

The US magazine industry is already in a brutal bidding war for the first baby pictures, with offers reaching six figures, says James. “And this will continue for milestones like birthdays, christenings, holidays and school events,” he adds. Already 31-year-old Kim has started sharing details, telling E! News that pregnancy is “not fun” and she’s having “growing pains”.
