Heather Morris is expecting a second boy.
The former 'Glee' star revealed in August that she is pregnant again and has now shared that the baby will be a little brother for her son Elijah.
She told E! News: "I'm having a boy. Elijah doesn't really understand the concept. I think he just thinks I'm getting a big tummy. He's really cute around babies and baby dolls and I adore it. 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."
Heather - who is married to Tyler Hubbell - shared the pregnancy announcement on her Instagram page by showing off her tiny baby bump from the side as she posed alongside a large blue ruler which read 'The Growing Hubbells'.
She also used the hashtag TheGrowingHubbells to caption the picture.
Among the first to offer their congratulations to the couple was Heather's former 'Glee' co-star Naya Rivera, who recently welcomed her first child with husband Ryan Dorsey.
She tweeted: "SO exciting! Congrats @HeatherMorrisTV #thegrowinghubbells.(sic)"
After welcoming Elijah into the world, Heather - who married childhood sweetheart Tyler in May - decided not to return to 'Glee' for the fifth series, though she reprised her role as Brittany Pierce for the 100th episode and the programme finale.
She has previously spoken of how much she adores parenthood.
She said: "I love being a mom. Boys are the greatest."
