Inside Leah and Brandon Jenner's Baby Shower

— -- Leah Jenner kept up the suspense at her pink and blue baby shower over the weekend.

Jenner, and husband Brandon Jenner, the son of Bruce Jenner, celebrated the upcoming birth of their first child at a shower thrown by their moms at their Malibu home Sunday.

Guests hoping to learn the sex of the baby were kept guessing at the outdoor shower, which was decorated with pink and blue balloons and pink and blue onesies stretched along a clothesline suspended between the trees.

Jenner didn't offer any clues either, posting a picture of dozens of pink roses being delivered the day before the shower alongside a snap of a stack of Sprinkles cupcakes wrapped in blue ribbons.

On the day of the shower, guests, including Brandon's brother Brody, feasted on salads, sandwiches and a bevy of deserts, and played games.

Bruce's ex-wife and Brandon and Brody's mother, Linda Thompson, posted several pictures and videos from the shower online.

"Imagine my joy & gratitude that @brandontjenner & @leah_jenner are blessing our family with a baby soon," Thompson wrote, alongside a video of the shower. "Leah's mom & I are throwing this delightful baby shower for them at their home. It reflects all the warmth & beauty their souls embody. #thankyouGod"

In another video, Thompson shows off the delicious food.

"@leah_jenner & @brandontjenner's gorgeous homey home as the back drop for her baby shower. Games food fun!!" she wrote.

One of the games involved a little fun with diapers.

"A funny little diaper game we played at @leah_jenner 's baby shower today," Thompson wrote, alongside a snapshot.

Thompson also showed off the desert table, which included a cake with "Welcome Baby Jenner" written on top.

Finally, Thompson posted a photo of her blooming daughter-in-law.

"I am grateful for this girl @leah_jenner & that she was so happy with the baby shower her mom & I gave her today," she wrote.
