Christina: With rumors swirling that she is pregnant, everyone's favorite dirrty girl, Christina Aguilera, made a visit to a maternity doctor on Thursday. Baby on board?! Casually dressed and sporting dark sunglasses, Xtina and hubby Jordan Bratman had their driver drop them off at NY's Maternal Fetal Medicine Association -- a practice known for their expertise in high-risk pregnancies and state-of-the-art ultrasounds. Guess we know what this girl wants! http://www.tmz.com/2007/06/08/does-xtina-have-a-genie-in-the-bottle/ Nicole: Nicole Richie's dad is a little out of touch with his tabloid fodder daughter. TMZ spotted Lionel outside of Mr. Chow last night, where our photog asked the "Dancing on the Ceiling" singer if there was any truth to the rumors that Nicole was preggers. Lionel's response -- "I don't know, I'll find out myself!" Also in the mood for some chicken dumplings: Bernie Mac, a dancing Stevie Wonder and "Beetlejuice" himself, Michael Keaton. http://www.tmz.com/category/nicole-richie/ There's also more about nicole on perezhilton.com. If these rumors are true I would say congrats to Christina, but as for nicole...well, I'll keep my thoughts to myself.
