Keibler, 34, took to her website Friday to announce that she gave birth to daughter Ava Grace Pobre.
"Jared and I have been blessed with the new love of our lives. Ava Grace Pobre was born at home on Wednesday, August 20th," she wrote alongside a picture of three hearts. "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 actress and her husband Jared Pobre, a tech entrepreneur, wed in a beach ceremony in Punta Mita, Mexico in March.
"We're really eager to start a family. ... Both Jared and I didn't think that we were ever going to get married or have kids… When you meet the right person, everything changes," she told People in March when she announced her pregnancy.
