Inside Big Brother Alums Brendon and Rachel Reilly Villegas’ Adventure-Themed Baby Shower

Brendon Villegas and Rachel Reilly‘s adventure-themed baby shower was perfectly fitting for the Big Brother and Amazing Race alums.

The couple, who are expecting their first child together this spring, prepared for the exciting arrival of “#BrenchelBaby” with a “magical” family- and friend-filled shower at their California home on Saturday. At the shower, the pair revealed that they are expecting a daughter.

Villegas, 35, and Reilly, 31, tell PEOPLE they let their guests get crafty at the party.

“We had them help make an ABC book for the baby girl,” Reilly says. “We had a craft table where they could make baby tutus, baby barefoot sandals and baby headbands and decorate onesies.”

But the fun didn’t stop there.

“We had face painting and flash tattoos for the kids. We had a popcorn bar, an amazing sweets table and lunch with mimosas, virgin cocktails and beer for the boys,” Reilly continues. “We played a few games and people had to guess the size of my belly — 38 inches.”

The backyard of the party also featured a handmade teepee and other decorations that go along with the theme of the nursery.

In a video from the shower, Reilly shares that they don’t have a name picked out yet — but she doesn’t want it to be a common one.

“Brendon thinks I’m gonna have a dream in the middle of the night that is gonna magically tell me the name,” she jokes, before adding, “I really want a unique name, so anything that’s on-trend.”

Villegas has different ideas, however: “What’s cool today may not be cool in 20 years, and guess what? Our daughter has to deal with this name for the rest of her life,” he says.

The reality TV couple announced the big news exclusively to PEOPLE in September.

“We’re so excited for this new adventure! After competing on four reality shows, we feel like we’re prepared for this new challenge. We found a way to make another lifelong alliance member and we couldn’t be more overjoyed,” they said at the time. “We can’t wait for the Brenchel Baby to arrive.”
