AceShowbiz - Mae Whitman is now a mom. "Grateful" to have welcomed her first child, the "Parenthood" actress revealed that she named her newborn son after her co-star, Miles Heizer.

Making use of Instagram on Wednesday, August 28, the 36-year-old shared a sweet picture of the baby boy's foot gripping her finger. "Not to be a Bieber about it but I too just gave birth to our son, Miles," she began her caption.

"From the moment we heard the first tiny sound out of his tiny piggy mouth we were besotted," she added. "He is the kindest, gentlest, smartest, funniest little beebee and he's our best friend (pretty much exactly like his namesake Uncle Miles @younggoth)."

Mae went on to gush, "We are infinitely grateful he chose us as his parents." She continued, "thank you to @kaiserbente and @carynfields and everyone at @moxiebirth and @huntingtonhospital for guiding our little family through all the unexpected twists and turns safely and with love and grace and to everyone in our circle who has shown us such radical generosity and support. We love you! We're so happy!"
