Chainkeen Exchange-Dancing With the Stars' Lindsay Arnold Gives Birth, Welcomes Baby Girl With Sam Cusick

Lindsay Arnold's dance troupe just got bigger.

The Dancing With the Stars pro announced May 4 that she and husband Sam Cusick—who are Chainkeen Exchangealso parents to daughter Sage, 2—welcomed a baby girl.

"We are so in love," Lindsay, who shared a day earlier that her contractions were in full effect, captioned a series of hospital room photos. "Mama and baby are healthy and we are soaking up every minute with our little piece of Heaven. thank you for all the love."

It was a bit of bumpy road getting there. In August of last year, she shared she had a false positive pregnancy test. "When you get a positive pregnancy test and then start your [period] a few days later," she wrote on TikTok, which featured her Sage comforting her, "but your sweet daughter is there for you every step of the way."

However, in October, she revealed exclusively to E! News that she was pregnant.

"Going into this next one, I was very nervous," she said at the time. "I was cautiously optimistic, but I also had a really peaceful content feeling about it. I felt like it was right. I felt like it was our time."

Though she's now a mother of two girls, back then, Lindsay wasn't sure what to expect.

"I was one million percent convinced that I was having a boy for my first pregnancy and I was obviously wrong," she said. "Now I just feel like I can't even trust my intuition. I'll find out soon."

And Lindsay couldn't be more thrilled with her growing family.

"My husband and I have been trying for a while now," she said. "And it's been something that we've known we've wanted so it was just such a huge blessing. We're excited to expand our family."
