Olivia Munn's husband draws attention from Taylor Swift video after she shares her cancer journey

An old awards-show clip from the early 2010s featuring Taylor Swift and Olivia Munn has gone viral, drawing millions of views.

The video was shared alongside misleading claims about Munn’s personal life. Shared in December 2025, by an X account, Taylor Swift Defense Attorney, the clip re-emerged after the actress recently praised her husband, John Mulaney, for supporting her during cancer treatment. 

The clip was used to imply that John Mulaney was cheating on her wife with Olivia Munn before his split from Anna Marie Tendler. 

During a recent interview with CBS Sunday Morning, Munn opened up about how her husband brought laughter, devotion, and daily support when she was confronted with the “possibility of death.

“There’s no better person in the world to me than my husband,” Munn shared, noting that he attended “every single doctor’s appointment.”

She recalled how he carried a notebook, jotting down jokes and observations about cancer and hormone therapy to lighten the mood.

“Having the humor to go through it and having someone who is so funny—it just lightens everything,” she said.

She praised Mulaney for balancing fatherhood with caregiving, from taking their son Malcolm to the park to returning to Cedars Sinai to sit with her late at night.

“He did it all happily,” she added.
