Actress Tamera Mowry-Housley is ready to pop and can’t wait to have her baby.

The “Sister, Sister,” star is expecting a boy, due on Oct. 30, with husband, news correspondent, Adam Housley. The couple married in May 2011.

“I can now say that I am down to the wire. I seriously feel like I have been pregnant forever. Almost 10 months to be exact!” Mowry-Housley wrote in a post for People.com mommy blog Mom’s & Babies.

“Thirty-nine weeks in and no baby yet. “This has now become a waiting game,” my OB told me.”

Tamera and her twin sister Tia Mowry-Hardict spoke to US Weekly on Oct. 18 during the launch of Tori Spelling’s children’s clothing line, Little Maven.

Tia who will serve as Tamera’s labor and delivery coach says her sister plans to have a natural childbirth; however, she is not confident Tamera will be able to stick with that plan.

"She is my sister and we can't take pain. Pain and us, we just don't mix!" Mowry-Hardict told Us Weekly. “"She is trying to be brave, which is good . . . but I don't think she is going to make it."

The younger twin, yet more experienced mommy, delivered her son, Cree via C-section in 2011. Mowry-Hardict married actor, Cory Hardrict in 2008.

She and Tamera star in the Style Network reality show “Tia & Tamera” that followed Tia’s pregnancy and Tamera planning her wedding. In the currently airing second season, Tia attempts to navigate motherhood and Tamera juggles newlywed life and maintaining her career.

In episode 19 that aired on August 27, Tamera discovers that she is pregnant. Mowry-Housley had actually found out months earlier in April, and revealed that she was having a boy in June.

Now, with her due date just one day away, Mowry-Housley discusses on her blog that most mothers do not have their babies on their due date; and many first time moms tend to deliver after their due date.

She says her little one has already taught her an important lesson about motherhood.

“Oh, what fun. If I have yet to learn patience, my son is in the process of teaching me now. I have learned that I am not in control and that he will decide when he comes,” she wrote.

“However, I have not been as receptive as I want to be to his timing. If I am completely honest … at this stage, I want this baby OUT!”
