Jessica Simpson rang in her daughter Birdie’s 4th birthday with a unicorn-themed bash.

The singer posted party photos via Instagram Thursday, praising the “magic” little one.

“This adorable wonder of a unicorn kiddo illuminates every color in the rainbow,” she wrote.

“She is uniquely and effortlessly herself,” Simpson, 42, continued. “This little lady celebrates and twirls through her life in tutus with a pure unique understanding in her soul of glitter sparkles.”

The “Newlyweds” alum concluded by calling Birdie a “symphony of STARDUST … born to SHINE.”

She gushed, “I smiled the entire time writing this because even when she isn’t home, I feel her presence glowing inside of me. Bird puts the HAPPY to the BIRTHDAY.”

In photos from the celebration, Simpson smiled in a furry purple coat and colorful dress while posing with her husband, Eric Johnson, and their eldest two children, Maxwell, 10, and Ace, 9.

As for Birdie, who turned 4 on Sunday, the guest of honor sported unicorn face paint, a bedazzled purple dress and a pink jacket.

Her party was a colorful affair featuring a unicorn cake, a candy station and metallic balloons.

In addition to the epic event, Simpson gave a glimpse at Birdie’s morning when family members woke up the birthday girl with doughnuts and party hats.

The “Dukes of Hazzard” star and Johnson, 43, welcomed Birdie in 2019, two years after Simpson joked to Ellen DeGeneres that she was done having kids.

She called baby No. 3 a “surprise” in her 2018 pregnancy announcement.

Once Birdie joined the family, Simpson told People that raising three children was “no joke” since they were all in “such different phases.”

She explained, “It is definitely constant, and the biggest challenge for me is trying to be present when I am pulled in so many directions.”

With so much “dividing and conquering” happening in her house at the time, the actress noted her intentions to continue to “connect” with Johnson.

The couple have been married since 2014. Simpson previously wed Nick Lachey in 2002, divorcing the 98 Degrees member four years later.
