'The Big Bang Theory' season 10 episode 11 spoilers: Bernadette to give birth to a baby girl?

Bernadette (Melissa Rauch) is giving birth to a baby girl. Meanwhile, Sheldon (Jim Parsons) shows Amy (Mayim Bialik) how affectionate and sexy he can be for his girlfriend.

Previously on "The Big Bang Theory" season 10, Bernadette went into labor and was brought to the hospital by Howard, Raj (Kunal Nayyar), and Stuart (Kevin Sussman) to give birth. According to a source who attended the taping of episode 11, titled "The Birthday Synchronicity," Bernie and Howie (Simon Helberg) will be having a baby girl.

In a forum on "The Big Bang Theory" fansite, Maddie shared the details gathered from the person who attended the episode 11 taping. According to the post, Bernadette will be sent home because her contractions aren't far apart yet to deliver the baby.

So Bernadette and Howard, along with Raj and Stuart, return to the Wolowitz house. Raj will start filming Bernadette and Howard anticipating the birth of their baby. But he gets on Howard's nerves, and he accidentally reveals the sex of their baby when he tells him, "What? I want her to know."

The newborn Wolowitz will be named Hallie, and unfortunately, she will have the voice of Howard's mother.

Meanwhile, Sheldon and Amy have their own thing going on while the whole gang is waiting for Bernadette's baby. Apparently, it will be Amy's birthday, and Sheldon will have a few surprises for her.

Sheldon will be greeting Amy at midnight, and his gift is an MRI scan of his brain. He will show him the part of his brain that lights up every time he thinks about her. The two start to get things going when the news of Bernadette in labor interrupts them.

The two will have a few more interruptions, but at the end of the episode, Sheldon and Amy will finally get into their annual coitus celebration.

"The Big Bang Theory" season 10 episode 11 is set to premiere on Dec. 15.
