Step Inside 20 Celebrity Baby Showers!

Kim Kardashian was the guest of honor at a garden-themed brunch in Beverly Hills prior to baby North's birth last June. The shower brought out celebrity pals Nicole Richie, Kelly Osbourne, Mel B, and trainer Tracy Anderson, as well as Kim's family. Her sisters Khloé and Kourtney were on hand, and proud papa Kanye West made an appearance despite reportedly being nervous about being the only guy at the party. It was an especially exciting day for the Kardashian family since it coincided with the season premiere of Keeping Up With the Kardashians, during which the sex of Kim and Kanye's baby was revealed. Kim shared that she's having a girl during the episode, adding, "That's really what Kanye has always wanted — he wanted a little girl."

Molly Sims's garden baby shower was as unique as the actress is herself. Rather than play traditional baby games, Molly had her guests create their own signature scents (including one she could take to the hospital for her delivery) at an essential-oil perfume station, write letters to the baby-to-be to be opened on each of his birthdays for the next 50 years, and start a bead project where each attendee brought a bead symbolizing something that meant a lot to them as a mother. The beads were then strung together to create a necklace for the mom-to-be.

Baby showers don't necessarily have to be all-girl affairs. To celebrate Drew Barrymore's baby, Olive, Cameron Diaz threw her best friend a coed backyard baby shower complete with a bouncy house for the kids, pool games for the guests, and chips and salsa for everyone to munch on throughout the afternoon.

While pregnant with her first daughter, Honor, Jessica Alba was feted with a shower at the Ever After Teahouse in Los Angeles. Guests at the beautiful party left with goodie bags filled with organic baby food.

Though Giuliana and Bill Rancic threw themselves a gender-reveal party, the mom-to-be was feted with a surprise baby shower thrown by her colleagues in their E! TV offices. The party was a complete surprise for the usually-in-the-know TV host.

Prior to the arrival of baby Ace, Jessica Simpson was the guest of honor at a Tom Sawyer-themed shower at the Hotel Bel-Air. The guest list included celeb friends like Jessica Alba, Chelsea Handler, and of course aunt Ashlee Simpson.

After adopting baby Eloise in 2011, Denise Richards turned to celeb party planner Mindy Weiss to throw a baby shower based on the books with the same name. The party included pink and black flowers (like the illustrations in the book) and a three-tier cake topped off with three figurines made to look like the guest of honor and her two big sisters.
