Christina Aguilera may have kept her pregnancy under wraps for months, but she couldn't wait to share details of her bouncing baby boy's "very joyful" debut Saturday night at Cedars-Sinai in Los Angeles. In a message posted on her Web site Sunday, Mrs. Jordan Bratman revealed that Max Liron Bratman weighed in at 6 pounds, 2 ounces. Liron? Yeah, we were wondering about that, too. Turns out the Hebrew-based moniker roughly translates to "my song," an appropriate choice for the Grammy-winning chanteuse and her music exec hubby. Christina also debuted a "special video" for her song "Save Me From Myself," which features personal footage from their 2005 wedding. "Just a little something to say 'thank you' for your undying love and support," gushed Aguilera. "It is in no small part because of you that I live such a blessed and wonderful life!" Check out the video here.

Also huffing and puffing inside the Cedars-Sinai maternity ward was Nicole Richie, who delivered a 6-pound, 7-ounce bundle of pink-swaddled joy on Friday. Nicole and boyfriend Joel Madden went the three-name route for their daughter, dubbing her Harlow Winter Kate Madden. Why Harlow? "There's a huge trend, especially among young Hollywood, to honor classic Hollywood with names," a baby name expert (yes, there is such a thing) posits to Us. "Harlow is the coolest glamour girl name." No word on whether the new parents are big fans of seminal blond bombshell Jean Harlow, although they aren't the first to choose the cinematic appellation. Patricia Arquette and Thomas Jane have a 4-year-old daughter named Harlow.

Nic's 'Book of Secrets': Buy low, sell high

Nicolas Cage won't have to worry about a return appearance from the naked intruder nabbed inside his Newport Beach, Calif., mansion last October. Not only was the interloper in question sentenced to a rehab program last week, but the Oscar-winning action star has also unloaded the estate for a hefty profit. The Wall Street Journal reports Cage pocketed an eye-popping $35 million for the waterfront compound, a record for Orange County. The actor, who owns several properties around the world, including a Bavarian castle and a Bahamian island, paid about $25 million for the house in 2005.

Lauren Conrad insists she wasn't given the heave-ho from her "Hills"-chronicled intern gig at Teen Vogue. "No, no, it was a decision I made because I was kind of done," she tap-dances to People. "I've been doing it for about two years, so I'm kind of done."

Waiting on the world -- and the number of DUIs -- to change

On Sunday, Oscar-winning "Pulp Fiction" screenwriter Roger Avary was booked on suspicion of DUI and manslaughter following a crash that injured his wife and killed a passenger. He joins an ever-growing list of busted Hollywood types, an ignoble club to which John Mayer hopes never to be admitted. In a message posted last weekend on his blog, the crooner recounts his designated driver-centric adventure while out on the town Thursday night with pals. Mayer recalls how he was feeling "wonderfully buzzy" after downing some smooth scotch, but when it came time to call it a night, he had a problem finding someone clear-headed enough to get his car back home. That prompted him to call his housemate Chad for a ride -- at 2 a.m. "Here's what I want to tell you," he writes. "If I, incredibly hot/fugly John Mayer can make that call, so can you. The distance from the parking lot to my house was about 5 miles, mostly straight shot up the coast of Santa Monica, zero traffic. And I didn't drive it. Me. The guy who gets the VIP velvet rope treatment in life." Says the lately Minka Kelly-free singer-songwriter, "I'm not writing this to earn golf claps, it's just that if I'm going to stand in any way as an ambassador of something cool or influential, this is more important than any pair of sneakers or a guitar."
