Olivia Munn and John Mulaney reportedly quietly married at the weekend

An insider told People on Wednesday (10.07.24): "Only their son and a witness were in attendance."

The pair's apparent nuptials come four months after Olivia publicly revealed her "terrifying" breast cancer diagnosis.

She also recently had her eggs frozen for future IVF procedures before she had a hysterectomy in case her chemotherapy treatment affected her fertility.

Olivia and John last month sparked marriage rumours when the comedian uploaded a picture of himself wearing a wedding ring - before he quickly deleted the snap.

He got together with Olivia in the wake of his split from his artist ex-wife Anna Marie Tendler, 39, to whom he was married for seven years.

The couple had their son in 2021, a year after former 'Saturday Night Live' writer John went to rehab and got divorced.

He went public with the pregnancy on 'Late Night With Seth Meyers', after Seth had been part of his substance abuse intervention in 2020.

John told his TV host friend, 50, he and Olivia had an "incredible" relationship, adding: "Olivia and this baby have helped save me from myself in this early journey out of recovery."

John went into rehab for cocaine addiction and alcohol abuse for 60 days in December 2020, Page Six reported.

Olivia has said her body is scarred with "divots and dents" after her breast cancer fight.

The actress told People about being left with "battle wounds" from her gruelling hysterectomy: "I have some divots and dents on one side of my body near where the lymph nodes were, and they had to really dig out.

"And I've been wearing some dresses on the red carpet that made me a little stressed out at times."
