Mae Whitman Kept the Identity of Her Baby’s Father, Carlos Valdes, a Secret for 6 Months

After playing a daughter on Parenthood, Mae Whitman is now a mother herself. The TV star announced the news on her Instagram page, saying that she had decided to name her son after her Parenthood co-star.

Following the news that Mae is now a mother, though, many naturally wondered who Mae's baby's father might be. Here's what we know about the dad of her first son, and what she's said about her new baby.

After six months of fans wondering who Mae's baby daddy is, her former on-screen mother and Parenthood co-star, Lauren Graham, revealed his identity in the most mom way imaginable. While appearing on Dax Shephard's Armchair Expert podcast, Lauren shared that she hadn't seen Mae in a while due to her moving to New York for her baby's father, actor Carlos Valdes' Broadway gig.

"They're in New York now. Carlos, her baby daddy, is on Broadway in Hadestown," Lauren confirmed before doubling down on his identity. "Which I feel happy to plug because he's fantastic in it, Carlos Valdes."

Per Entertainment Weekly, Carlos and Mae connected when they played on-screen lovers in the short-lived Hulu series Up Here. It's unclear when they started dating, but the Good Girls alum has shared photos of them together, including a snap of them protesting during the SAG-AFTRA strike.

Before his name was revealed, Carlos also shared with People in March 2025 that he was a "a relatively new dad" and was balancing his new responsibilities with his Broadway career. The actor's other credits include The Flash and Supergirl.

Mae made the announcement that her son had been born on Instagram, writing, "Not to be a Bieber about it, but I too just gave birth to our son, Miles." Mae also revealed she named her baby Miles after her co-star in Parenthood, Miles Heizer, who played her brother on the series.

"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 [Heizer])."

Mae and Miles have remained close since Parenthood. They have also remained close with their onscreen mom, as she mentioned above. In fact, the post announcing that Mae was pregnant featured a picture of her with both Lauren and Miles.

Mae's close relationships with her Parenthood co-stars are evident on her Instagram page, but she has been careful to avoid posting pictures with people from her personal life who aren't already well known to the public. Mae seems determined to keep her family life relatively private, and her social media followers have thus far respected those boundaries.

Mae is not a frequent poster on social media, but she has shared major life updates there regularly. Now, the biggest life update of all has happened, and she seems to be thrilled about it. While some people may wonder who the father is, most of the people in her comments are just congratulating her on Miles's arrival.
