Sasha Pieterse has a baby on the way.

On Wednesday, the “Pretty Little Liars” alum announced she is pregnant and expecting her first child with husband Hudson Sheaffer, two years after they tied the knot.

“We are so beyond excited to finally share our sweet news with all of you ✨ we will be welcoming a precious little human this October!” Pieterse shared on Instagram, posting a photo of Sheaffer kissing her growing baby bump.

“Today marks our 2nd wedding anniversary and what better way to share our joy then on the day when our lives changed forever (the first time 😉) Motherhood is officially my favorite role ever!” she continued.

Pieterse, 24, married Sheaffer, 30, at Castle Leslie in Glaslough, Ireland, in May 2018. They got engaged three years prior.

“@hudsonsheaffer thank you for making me a mom and for always being my unwavering rock and safe place,” Pieterse wrote. “You bring out the adventurer in me and I feel like my truest self when I’m with you, luckily that’s all the time!”

She added, “I love every part of you with every part of me and will continue to love who you are and who you become especially as we enter this brand new chapter.”

Pieterse isn’t the only “Pretty Little Liars” star embracing parenthood. In October, Shay Mitchell gave birth to daughter Atlas. She was in labor for 33 hours.
