You know what Hollywood loves? Babies.There's been a veritable baby boom recently, which will be very exciting in years to come-Halloween baby costumes and birthday parties, anyone?

Model and reality TV host Heidi Klum gave birth on Oct. 9 to daughter Lou Samuel, her third child with husband Seal and her fourth child overall. Lou joins siblings Johan, 2 1/2, Henry, 4, and Leni, 5. Auf wiedersehen, maternity clothes: Knowing Heidi, she'll be back on the runway in no time at all.

Amy Ryan, star of NBC's hit show The Office, joined in on the baby?boom Oct. 15 with the birth of her daughter Georgia Gracie Slovin. Born in New York City, baby Georgia is the first child for Ryan and her fiancé, Eric Slovin, who plan to wed later in the year.

Supermodel and G.I. Joe actress Karolina Kurkova welcomed a son this Thursday in New York. Her husband, film producer Archie Drury, confirmed the birth to People magazine early on Nov. 1. The baby boy, named Tobin Jack Drury, is the first child for the couple. Apparently, there's been a bit of a mini baby boom among Victoria's Secret models-the birth comes just two weeks after Kurkova celebrated her baby shower with actress Michelle Monaghan and fellow Victoria's Secret models Alessandra Ambrosio and Adriana Lima (who is also expecting) at Abe & Arthur's restaurant in New York. Ambrosio, who had a daughter last year, says the Victoria's Secret models are baby crazy. "It's just great that we're all at the same time in our lives. We're all having babies, we're thinking about play dates. We're going shopping for the babies," she says. "If we have time, we're together talking about babies!"

Mel Gibson's girlfriend, Oksana Grigorieva, gave birth to the couple's first child on Oct. 30. Even though the baby arrived early, a rep for the couple told RadarOnline.com that both mother and daughter are doing just fine. The arrival of his newest makes Gibson an Octo-Dad: he has seven children (six sons and one daughter) with his estranged wife, Robyn. This isn't the first for Grigorieva, either-she has a 12-year-old son with actor Timothy Alcon.

Mazel tov to all the new parents! For the sake of the diaper stores and ob-gyn offices in the New York and Los Angeles areas, let's hope things calm down for a little while.
