Just call him Grandpa Ian!

"The calm before the storm...Launching Season 5 of The Vampire Diaries&preparing for the launch of a whole part of life-being a GRANDFATHER," Ian Somerhalder wrote on Instagram Thursday."

The Vampire Diaries star, who posted a photo of himself laying on the floor with his dog Nietzsche, revealed his pup is going to be a mom...and really soon.

"Yup-I've got my hand on a belly with 8 little ones about to explode out into the world.What I thought was one rescue become 9-Mama Nietzsche is a trooper-babies coming in about 48hrs... Aunt @thejram & Uncle @polivierjr GET READY for some BABIES! 2 cats 9 dogs- is that considered a hoarder???," Ian went on.

Perhaps a few of Ian's numerous pets can be housed in the animal rescue center he's planning on opening.

"We're building an animal sanctuary that's also going to double as a sustainable agriculture farm and triple as a youth education camp," he said in a video with Josie Maran recently. "When a young person comes to that farm, they leave with a different understanding of compassion. If you have compassion for an animal, ultimately you will have compassion for people."

The 34-year-old actor rescued Nietzsche after he found her wandering in traffic near the set of the Vampire Diaries, and shared the news with his fans after he decided to take her home.

"My new girl," Ian posted on Instagram in August. "Rescued from traffic near the Vampire Diaries stages just a few hours ago. so smart, so beautiful&charming-all a man could ask for in a girl-So happy together.Her name is Nietzsche."
