Dermot Mulroney: Lip Scar, Sobriety, and Hollywood Friendships

You’ve seen him in My Best Friend’s Wedding, or maybe on Friends, playing the charming guy next door. But behind those roles is a real person with a scar he’s never hidden, a battle with addiction he’s learned to talk about, and friendships that have lasted decades.

Born: October 31, 1963 · Occupation: Actor and musician · Children: 2

Six key facts at a glance, with a clear divide between what’s documented and what remains open.

What Happened to Dermot Mulroney’s Lip?

Origin of the scar

The thin line above Mulroney’s upper lip is the result of a childhood surgery to correct a cleft lip. IMDb (film database) notes he was born with a cleft lip, which was repaired in infancy. The scar has been visible throughout his career, but he has never tried to hide it.

Has he addressed it publicly?

Mulroney rarely discusses the scar in interviews. The subject has not been a focus of his public appearances, leaving the medical specifics—such as the exact type of cleft or number of surgeries—undocumented. The pattern: the scar is known, the details are not.

Is Dermot Mulroney Sober?

In a 2023 Facebook post, Mulroney shared that “getting sober” was a milestone in his life. The post, quoted by Page Six (celebrity news), marked his first public acknowledgment of addiction struggles. He has not specified the substance or length of his sobriety.
