He's spent decades building a bombshell portfolio, but Cavalli may now go down in history for something else: Confirming to the world that Jennifer Lopez is pregnant. The Italian designer let the baby news slip during an interview with People magazine, saying "Well Jennifer Lopez, at this moment, she requests something very special because she is waiting for the baby... It is so complicated because every week she is getting bigger." It's such an obvious slip that many may think Cavalli did it on purpose for the publicity, but we've met the gallant designer several times, and think the well-tanned Italian does well enough without violating stylist-client confidentiality. Instead, here's our theory: Cavalli spilled the beans during an interview about his new vodka line, so perhaps he was just a little tipsy. PS - While the designer may have fumbled in the celebrity "secret" department, he certainly knows how to party - check out his Karl Lagerfeld Halloween costume from Cipriani last night!
