Alanna Masterson is having a baby! The 27-year-old "Walking Dead" star is expecting her first child with photographer and boyfriend Brick Stowell, according to People. On Monday, she posted an adorable baby bump shot to her Instagram looking stunning in a white dress.

"Guess what..." she captioned the photo with a baby emoji, tagging her boyfriend.

Stowell then posted another photo of his own announcing the news. In the mirror shot, captioned "baby season," Masterson is wearing a white bikini, once again showing off her growing belly.

Considering the size of her bump, and the fact that she's been pretty much an expert at hiding her belly in recent photos, she's definitely known the news for sometime. It is unclear just how far along she is, though.

With season six of the hit zombie show premiering October 11, it is unclear how the pregnancy will be dealt with on the show with her character Tara, according to Daily Mail. It has not yet been announced if they will be addressing it at all in the storyline or if they will just be hiding it.

Congrats to the happy couple!
