“Dancing With the Stars” pro Lindsay Arnold has given birth to her first child with husband Sam Cusick, a girl.

“The most beautiful surprise on this very special day,” Arnold, 26, wrote on Instagram Monday alongside a picture of the three. “Baby Girl and mama are healthy and well. More details to come but wanted to share this first pic of our little family.”

“DWTS” friends weighed in immediately. “My heart,” Witney Carson commented, adding, “She’s so perfect in every way! SO SO HAPPY FOR YOU TWO! I can’t wait to snuggle her!”

“What a BEAUTY!” Peta Murgatroyd wrote.

Arnold and high school sweetheart Cusick, who married since 2015, announced the pregnancy in May, revealing the sex of the baby a week later.
