“I am really, really, happy,” JoJo said in an Instagram video on Saturday.
“I always believed that my person was just going to be my person,” she went on. “And if that person happened to be a boy, great, and if that person happened to be a girl, great!”
“I always knew the world would be a more colorful, positive, sparkly place with a kind, loving, dazzling triple threat like you in it,” Abby Lee wrote.
“Love you kiddo!!!” she added. “Keep making me proud.”
