Olivia Munn's Son Malcolm Wishes Her a Happy Birthday in Sweet Video

Olivia Munn is getting some adorable love from her young son on her birthday!

Munn took to Instagram on Wednesday to share a video of herself on her 44th birthday, where she was staying out of the heat and celebrating the occasion.

"I'm spending my birthday morning in a tent," Munn began before her 2-year-old son, Malcolm -- who she shares with partner John Mulaney -- can be heard from offscreen declaring, "Happy birthday, Mommy!"

"Oh my gosh! Thank you so much, you’re the sweetest," Munn replies with a beaming smile, before asking, "Can you say, 'I love you, mama?'"

"I love you so much," the adorable toddler exclaims, to Munn's delight.

"Can I go inside the house and watch Red Panda?" Malcolm asks -- likely referring to the Pixar film Turning Red -- eliciting an off-screen laugh from Mulaney.

"What a year," Munn captioned the post. "Thank you for all the birthday wishes!!!"

This has certainly been a turbulent year for Munn and her family. Back in March, Munn revealed that she'd been diagnosed with breast cancer. Munn explained that she had already undergone a double mastectomy -- just 30 days after she was first diagnosed -- and was put into medically induced menopause. She has since had a hysterectomy and oophorectomy, which are procedures to surgically remove her uterus and ovaries. 

Sitting down with Michael Strahan on Good Morning America back in May, Munn said that she made an effort to document much of her experience to pass down to her child in the event that her treatment was unsuccessful. 

Munn and Mulaney were first romantically linked in early 2021, and the couple went public with their happy pregnancy news in September 2021. The pair welcomed Malcolm in December 2021.

ET previously spoke with Munn while she was expecting back in 2021, where she shared that she was excited to become a mom and welcome a baby into the world alongside Mulaney.

"I'm just excited about meeting whoever it is, and bringing a little person into this world," Munn said at the time.
