When Robert Downey Jr. welcomed his son Exton in February, people wondered how exactly he and his producer-wife Susan Downey came up with the baby's name, which is not something you'd hear at the playground all that often. Was it a place name? (There are Extons all over the map and the actor did name his 18-year-old son Indio after the California city where the Coachella music festival takes place.) Or perhaps those Jolie-Pitt boys inspired another "x" name? (Maddox, Pax and Knox are mini trendsetters, you know.) Well, we have finally have the answer courtesy of Downey himself.

The thing about trying to hide a pregnancy is … sooner or later you can't. Just ask Jessica Simpson, who, back in October, was already sporting a pretty big bump even though she wouldn't reveal the news at the time, or the usual trim-and-slim Reese Witherspoon, who got rumors going a few months back when she was spotted with a bit of a bigger belly. She's still mum on the subject.

Following the announcement that Maxwell Drew Johnson was born earlier this week, the "How I Met Your Mother" actress offered her well wishes to the "Fashion Star" mentor while also slipping in a one-liner that has been getting, well, belly laughs.

Cindy Crawford stars in a sweet Mother's Day ad campaign with her mother Jennifer and 10-year-old daughter Kaia Gerber for JCPenney. In the photo, all three ladies are casually dressed in jeans and white tops from the department store and appear to be laughing about something, as the supermodel links arms with her mother. "Oh my goodness, she's just the best mom in the world," the adorable little girl — who is the spitting image of her mother — says about Crawford in the accompanying video. "She's so nice, and I can actually hang out with her and have fun."

Simpson and Johnson (Aik Arshamian/INFphoto.com)Jessica Simpson and fiancé Eric Johnson's baby is only a day old and she's already cleaned up in the gift department! In addition to the high-end items the new mom received at her fancy, Charlotte's Web-themed baby shower in March, Jessica also received presents at the Los Angeles hospital where she gave birth to daughter Maxwell Drew Johnson yesterday.

Among the gift givers was her first husband, Nick Lachey, and his new wife, Vanessa Minnillo, reports HollywoodLife.com. "A large basket of pink and white cookies were delivered to Jessica's hospital room at Cedars-Sinai from Nick and Vanessa," a source told the website. "The basket was delivered by Cookies by Design and included seven huge cookies with adorable baby girl decorations." It was nearly a decade ago that Lachey and Jessica themselves were "Newlyweds." They divorced just three years later and he married Minnillo in 2011. Nick and Vanessa are expecting their first child this fall.
