Jessica Simpson is so proud of her baby belly that she’s showing it off on the cover of this month’s Elle magazine. Simpson is the latest star to recreate Demi Moore’s famous 1991 Vanity Fair cover, cradling her bump as one arm covers her breasts. In the magazine, Simpson reveals she and fiancé Eric Johnson are expecting a little girl, and she’s hoping the baby shares her tastes. “I swear, I will croak if she asks me for a pair of Nikes instead of Christian Louboutins,” said Jessica. “Eric is so athletic – we’re gonna have this athletic girl and I won’t even be able to take her shopping, ‘cause all she’s gonna want is sports bras and Nikes!” As for their daughter’s name, Jess said it will be “nontraditional,” but adds, “it’s nothing shocking and nothing you’ll have to add to the dictionary. Still, when people hear it, they’ll know…why.”

Sandra Bullock and director Brett Ratner are denying an In Touch magazine report that claims they are an item, and were recently seen packing on the PDA at an Academy Award after-party. "We think that it's incredibly sad that in these times, this magazine would resort to complete fabrication, solely for financial gain,” said the two stars in a joint statement. “There is not a shred of accuracy in their story. We have not seen nor spoken to each for over a decade. We both had a great time after the Oscars, just not with each other."

Whitney Houston’s daughter Bobbi Kristina will inherit the late singer’s entire estate, which is reportedly worth $20 million. According to a document obtained by Inside Edition, on April 14th, 2000, Whitney amended her will, leaving her daughter everything, including her money, furniture, clothing, personal effects, jewelry and cars.  The money will be placed in a trust for the 19 year old, and she’ll get some of it when she turns 21. Additional funds will be given to Bobbi Kristina when she turns 25, and then again when she turns 30. Houston’s mother Cissy was named executor of the will, while Whitney’s brother Michael and sister-in-law Donna are the trustees.

Sienna Miller tells British Vogue that she is “very excited,” to be expecting a baby with boyfriend Tom Sturridge. “I'm feeling fine,” she told the magazine. “It's all progressing nicely and it's very exciting.” Sienna, 30, didn’t want to open up too much to the magazine, because she’s trying to keep her personal life as private as possible. “I'm in my second trimester, so I'm I-can-talk-about-it pregnant, even though I'm under strict instructions not to say anything as it would completely defeat the point of everything I've tried to achieve in the last eight years,” she explained.  As for turning 30, Sienna seems to be okay with it. “I didn’t have the freak-out which I thought I would have,” she said. “But maybe it’s because I’m the youngest of all my friends – so that lessened the blow.”
