NBC’s This Is Us may be on winter hiatus, but Alexandra Breckenridge (who plays Kevin Pearson’s on-and-off love Sophie) is having a busy break! The actress gave birth to her second child with husband Casey Neil Hooper this month, and the new baby’s name is unique and adorable.

Billie Breckenridge Hooper was born earlier this month on Wednesday, December 6, a rep for the actress confirmed to People. Little Billie weighed 7 pounds, 13 ounces, and measured 20 inches long.

“We are so excited to have a boy and a girl!” the new mom told People. Breckenridge and Hooper are already parents to 15-month-old son Jack, and as the actress says, it’s the perfect age difference. “Billie is such a sweet baby girl and Jack is such a social boy, with them only being 15 months apart, they will always have a friend to play with.”

Breckenridge revealed that she was expecting her second child back in August. Recently, she admitted that she was initially afraid to reveal that she was pregnant out of fear of getting fired from the show.

“I was scared to tell them because I thought it would cause issues for production,” she told Us Weekly. “I called Dan [Fogelman, show creator] and said, ‘I’m sorry. I’m pregnant,'” she said. “He was just like, ‘Oh, that’s amazing! Congratulations!’ He’s so nice.”

Congrats to the growing family!
