Boy, oh boy! Pregnant former Glee star Heather Morris revealed the gender of her second baby-to-be in a recent interview, and it turns out that the actress will be welcoming a bouncing baby boy with her husband, Taylor Hubbell!

Morris, 28, told E! News her son, 2-year-old Elijah, is still trying to get used to the idea of having a baby brother.

“He doesn’t really understand the concept,” she said. “I think he just thinks I’m getting a big tummy.”

But, she added, there are already signs that he’ll make a great older sibling.

“He’s really cute around babies and baby dolls and I adore it,” she said. “He’s really excited to have somebody to play with because he’s at that age where he’s active and wants to do stuff.”

Morris first announced her second pregnancy back in August, via an adorable Instagram snapshot of herself next to a measuring stick that read, “The Growing Hubbells,” with her growing baby bump next to the “4” mark. The pair wed in May at Old Canyon Ranch in Topanga, Calif.

Fellow Glee alumni Naya Rivera — who welcomed her own baby boy with husband Ryan Dorsey in September — chimed in with her congratulations.

“SO exciting! Congrats @HeatherMorrisTV #thegrowinghubbells,” she tweeted at the time.
