Jessica Simpson wore a flashy leopard-print jacket, but all eyes were on her rumored baby bump as she stepped out of her NYC hotel this morning. Jessica covered up her stomach with another animal-print accessory and a bulky poncho when she hit the town last night. She is rumored to be holding out for a People magazine cover story to confirm her pregnancy, so we'll see when the new issue comes out tomorrow whether she's ready to reveal any big news. In the meantime, Jessica and fiancé Eric Johnson enjoyed a romantic getaway in Palm Springs, and she's been keeping herself entertained by sharing her thoughts on music and the trials of being a short girl on Twitter.

Jennifer Lopez and her sister Lynda teamed up today to support a good cause at a local Best Buy in LA. Lynda and Jen were on hand to accept a $500,000 check for their Maribel Foundation, which provides quality health care for women and children around the globe. Through Jen's partnership with Samsung and Best Buy, the organization will now be able to treat children in multiple countries with the use of cutting-edge telemedicine programs that can treat and diagnose illness under the guidance of doctors from Children's Hospital Los Angeles.

Shortly after the ceremony, Jen changed into a casual pastel top and pants for a meet and greet autograph-signing session with fans. The first 200 people in line at the store got their own signed Love? CD. She was in high spirits for this happy occasion, but over the weekend Jen broke down in tears. Reminiscing over past loves and seeing her mother in the audience during a performance of "Until It Beats No More" proved to be too much for the newly single singer. J Lo got extremely emotional following a choreographed routine with dancers dressed like former loves Ben Affleck, Diddy, and Marc Anthony, and according to the singer she's "just a girl, just like everybody else, trying to find [her] way." Meanwhile, Bradley Cooper might be just what Jen's searching for as the pair were recently spotted together returning to her Calabasas home.

Nicole Richie stopped to get lunch with her kids Harlow Madden and Sparrow Madden at LA's Cafe Med yesterday. The mom of two spent the afternoon with her little ones following a fun weekend, in which she and husband Joel Madden brought Harlow and Sparrow to pick out their pumpkins at a patch. Nicole evidently had music on while in the car, as she tweeted, "J Lo's new song just came on the radio, and I immediately thought of the Fiat. . . So I guess that commercial really worked." Nicole may make a TV spot of her own over the next year, as she'll have her first scent to promote. Nicole Richie's fragrance will be "cool and classy with an edge," though we won't get to sniff it until next Fall!

Ben Stiller, Eddie Murphy, and Matthew Broderick got together last night for the NYC premiere of their comedy caper Tower Heist. Sarah Jessica Parker, wearing a tiered Narciso Rodriguez dress and Manolo Blahnik stilettos, was out late on a school night with her 8-year-old James Wilkie to show their love and support to Matthew. Ben cozied up to his lovely wife, Christine Taylor, on the red carpet while costars Eddie, Casey Affleck, Gabourey Sidibe, and Tea Leoni posed for photos before heading into the Ziegfeld Theatre. The screening brought out a variety of famous faces like Serena Williams, Donald Trump, Doutzen Kroes, and Diddy. Director Brett Ratner moved the afterparty to Stone Rose Lounge where he and the stars of the film partied late into the night alongside Jason Sudeikis and Mary-Kate Olsen.
