Jason Kelce and Kylie Kelce’s daughter traveled under the sea for her 4th birthday!

On Sunday, the mom of three, 31, shared a few photos from daughter Wyatt’s mermaid-themed birthday party, which included vibrant decor such as teal, purple, pink and orange balloons. Kylie reshared a photo of her daughter on her Instagram Story as she played in a giant bubble house, surrounded by multicolored balloons.

“Wouldn’t be a proper mermaid party without a BUBBLE!” read the text on the photo, as Kylie added, “Peep Wyatt 👀 She was in love.”

Another picture showed a giant backdrop of a mermaid, made by Venus & High Volt Co., with the words, “Wyatt Turns Four,” written across the top.

Jason, 35, was also seen at Wyatt’s party, smiling in a family photo with his three daughters and wife. The Philadelphia Eagles center held daughter Bennett Llewellyn, 7 months, and stood next to Kylie, who held Wyatt and daughter Elliotte Ray, 2. Both the photos and the balloons were done by Charming Garlands.

In another photo, the couple’s two older daughters pose together in front of the mermaid poster, with Wyatt draping one arm around her sister Elliotte.

The football player was later seen adorably playing with daughter Wyatt in a giant balloon house, flipping her around and playing with floating balloons as she tugged at his beard.

Kylie later shared a few pictures from the party on her Instagram, taking a minute to honor her oldest daughter. “Happy Fourth Birthday to our sassy, opinionated, sweet, empathetic, and intelligent Wyatt!” she wrote.
