“Jared and I have been blessed with the new love of our lives. Ava Grace was born at home on Wednesday,” she writes.
“We’ve never experienced a level of joy and happiness like this before! Thank you so much for all of the special wishes and positive energy.”
The pregnancy was smooth sailing for Keibler, 34, who announced she and Pobre, a tech entrepreneur, were expecting a baby shortly after the couple tied the knot in March during a beach ceremony in Mexico.
“I haven’t had one day where I’ve been sick or tired,” Keibler told PEOPLE.
“Our bond is so strong and special and getting pregnant has made it even more so. It’s been so much fun preparing to become new parents together,” the mom-to-be said in May.
Weeks before baby girl’s birth, Keibler told PEOPLE she and Pobre were ready for her big arrival — and had already decided on a name for their daughter.
“We just talked about one name and that was it — easy peasy,” she said in July.
