The 34-year-old former WWE star gave birth to a baby girl, and the couple named her Ava Grace. Keibler announced the news on her website Friday.
"Jared and I have been blessed with the new love of our lives," she wrote. "Ava Grace was born at home on Wednesday. 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."
"My happiness is indescribable!" she told People after the wedding. "Marriage is the ultimate bond of love and friendship. It means putting all your faith and trust into a person that you can't help but believe is your soulmate. Someone who has all of your best interests at heart; someone handpicked for you, to help you grow and be the best person that you can be. Jared is all of this for me."
Keibler left the WWE in 2006, and has pursued a career in acting and modeling in recent years. She last appeared on How I Met Your Mother, and has also guest starred on Men at Work, Chuck and Psych.
