"Thank you for the Bday call today @JoJoSiwa!" Ciara wrote on Instagram. "Sienna was so happy to see you."
Just look at those balloons!
How much fun is Sienna going to have in this playhouse?
Sienna wore Elsa's blue gown for the special occasion.
"Nail shop for the princess," Ciara wrote alongside a photo of her daughter getting a manicure and pedicure.
Do you want to build a snowman...with marshmallows?
The day couldn't end without watching Anna on the big screen.
Happy birthday, Sienna!
