May 19 (UPI) -- Orange is the New Black alum Lauren Lapkus is going to be a mom.
The 35-year-old actress is expecting her first child, a daughter, with her husband, Mike Castle.
Lapkus shared the news Tuesday on Instagram alongside a photo of herself with Castle and their dog. The picture shows Lapkus and Castle looking into each other's eyes as Lapkus cradles her baby bump.
"We are expecting a baby girl this summer. I am over the moon. So grateful and happy," Lapkus captioned the post.
Lapkus included the hashtag "rainbow baby," a term used to describe a child born after a miscarriage, stillbirth, neonatal death or infant loss.
"Yayyyyy!!!! Congratulations!!! So so happy for you!!!" Chalke wrote.
"Oh, honey! Look at all the love," Handler said.
Lapkus played Susan Fischer on Orange is the New Black. She portrays Phoebe Donnegan on Good Girls, which returned for a fourth season on NBC in March.
