A baby is brewing for Nicky Hilton.

As the hotel heiress awaits the arrival of her bundle of joy, sister Paris and mom Kathy were on hand to throw the expectant mom the most lavish baby shower on Tuesday.

After welcoming daughter Lily Grace with husband James Rothschild last July, the 34-year-old is reportedly waiting to find out the gender of her baby this time around. And the Bel Air, Calif., bash offered both pink and blue cakes for the guests.

Older sister Paris—who donned a pink and white frock topped with a candy pink cardigan for the afternoon—took to Instagram to share photos from the event as guests like Kyle Richards and Bethenny Frankel arrived dressed in garden-themed attire.

The mom-to-be kept with the party’s color scheme by offsetting her sister with a blue printed maternity dress and turquoise drop earrings, while baby Lily kept things neutral in yellow-printed pajamas.

Alongside the tell-tale buttercream cakes, the Hilton women also set the clear dining room table with an array of delectable colored macaroons fruit tarts as well as finger sandwiches and pink lemonade.

In keeping with the holiday spirit, a pink Christmas tree was a stunning addition to the floral bouquets and candles that decorated the setting.

Let the countdown begin!
