News - Kay and Tay Dudley Welcome Baby and Reveal the Newborn's Name (Exclusive)

Kay and Tay's family just got a little bigger! The TikTok stars, whose real names are Kaylee and Taylor Dudley, welcomed another baby together on Tuesday, Oct. 7, sharing the news exclusively with PEOPLE. The new addition will join daughter Ellie, 23 months, and Kay's daughter Kinsley, 13, from a previous relationship. Kay and Tay's baby Sutton Dudley came into the world at 4:29 pm, weighing 7 pounds and 15oz. “We’re overjoyed to have baby Sutton join our family!,” the couple shared in a joint statement exclusively to PEOPLE. “It’s bittersweet that the pregnancy journey is over, but we can’t wait to start this new adventure, two under two!” The couple exclusively revealed to PEOPLE that they were expecting their second baby together in February. The newly minted mom of three shared that she found out the exciting news by herself. "I actually found out by myself," Kay told PEOPLE at the time. "I took a test and I was fully anticipating it to be negative. I've had very irregular cycles and I just...part of me was like, 'Well, I should take a test,' but I really didn't think it was positive." "I was trying to plan this really cool surprise for Tay, but I was so ready to tell him. So I ended up standing up with the most lame excuse. I was like, 'There's a bug up here,'" she remembered. "And he came up and was looking for this bug. And then I was just standing there with the test. It was lame, but it was fun."

When Tay heard the news, he shared with PEOPLE he was in "shock" because he thought he was just going to help squash a bug. "But then immediately after, it was excitement," he recalled. "We've wanted to grow our family, and so that's something that I want and she wants, and so just immediate joy and excitement. I'm still excited and still it doesn't feel like a real thing. We say all the time or Kay says all the time, she'll be like, 'I'm pregnant!'" After sharing the happy news with each other, the couple was excited to tell their family and friends — who were also just as shocked. "I think everybody's just so supportive in our life," Kay said. "Our friends and our family, and people that we've told, have cried. They've jumped for joy. Everybody's just all excited. I don't think we've told one person that wasn't shocked."
