Ian Somerhalder and his wife Nikki Reed are all set to welcome their second baby together.

The 44-year-old actor shared the good news with his 23.8 million Instagram followers Monday, confirming that his wife is pregnant again.

Somerhalder shared a photo of Reed flaunting her baby bump and holding their five-year-old daughter, Bodhi Soleil, in her arms. The actor revealed that he always wanted to have a big family and thanked Reed for the same.

"ROUND TWO HERE WE GO!!!!!" Somerhalder added. "Thank you thank you to this incredible human for the gift of life and love, for being the most incredible mom and working so hard to make dreams come true!!!"

The 34-year-old actress also shared the same photo on her Instagram handle and wrote, "2023 celebrating life. Years of dreaming, manifesting, and praying over this very moment. So much love. What a gift."

Reed noted that she has "very strong boundaries with social media, especially when it comes to children and what I choose to put out into the world. Thank you so much for honoring that, and for sending positivity and kindness and LOVE. Some things are too good not to share."

Since the pregnancy news was shared on Instagram, many celebrities flooded the comments section with congratulatory messages.
