Ah, the life of a Girl Next Door
: Exciting parties, glamorous photo shoots, your own TV show ... and getting sick in a limousine.
"I've thrown up in almost every limo that has taken me out in the last week," Kendra Wilkinson
tells E Online
of the first queasy three months of her pregnancy
. "God, they hate me right now."
Wilkinson, 23, who's been craving Top Ramen noodles and fruit, had originally planned on having a baby next June – a year after her June 27 wedding to pro football player Hank Baskett – but is "so happy" to be12 weeks along. "My doctor told me I'm due on Christmas Day!" she says. "The baby is going to be spoiled with a lot more gifts."
And the wedding is going as planned, though the Playboy model says she will have to make an alteration to her dress. "My boobs went from big to humongous," she tells E!. "They're making some changes in the bust."
