Broadway star Leslie Odom, Jr. is preparing to become a father for the first time.

The actor and his wife Nicolette Robinson announced the happy news on Instagram on Monday (17Oct16), when Odom, Jr. shared a sweet photo of the couple posing beneath gold balloons which spelled out the word "Baby".

"Little one, you're on our mind all the time. Keep eating and growing!" the 35-year-old wrote beside the snap. "We love you and we're already so proud of you! Love, your mom and dad."

The baby news caps off a great year for Leslie - he won a Tony Award for his former role as Aaron Burr in Broadway hit Hamilton, while he recently landed a big role opposite Johnny Depp in director Kenneth Branagh's new take on Agatha Christie classic Murder on the Orient Express.
