Mae Whitman might be a little upset at her former onscreen mom, Lauren Graham, because, like real parents sometimes do, she just spilled a big secret! Whitman, 36, welcomed her son Miles in August 2024 and managed to keep the father’s identity under wraps—until now.

While speaking to their fellow Parenthood alum, Dax Shepard, on the actor's Armchair Expert podcast, Graham accidentally revealed the father of Mae Whitman 's son: Carlos Valdes. While Whitman has never publicly shared the identity of the baby's dad, the pair did work together on Up Here.
