Los Angeles, California - Olivia Munn has given fans another intimate peak at her and John Mulaney's new baby boy.

Baby fever alert!

The X-Men: Apocalypse star posted a new sweet pic of her newborn son Malcom, while he gets a whole lotta loving from his pops.

On Monday, Olivia posted the heartwarming snap with the caption, "The smooshiest smoosh."

The 41-year-old also made a note of her Christmas tree in the background.

"And yep, our Christmas tree is still up," she added, noting the date being more than two weeks past Christmas.

Famous friends of the Deliver Us from Evil star wasted no time in commenting on the sweet pic.

"Bring him to meet the horses. Those lips. So adorbs," Charmed star Alyssa Milano wrote. "My tree is still up too."

Actor Ben Baller also jokingly commented, "We JUST took our Christmas tree down today."

This is the third time the world has gotten a glimpse of little Malcom, who is the first child for both Olivia and John and was born in November.

The pair's bundle of joy was first introduced to the world last month in a pic Olivia shared on IG. She soon posted a second photo of the ridiculously cute baby, in which the new mom is seen smiling ear to ear while gazing at her son.

Though Olivia and John have been keeping their official relationship status under wraps, they seem to be enjoying parenthood.

Only one week after his May 2021 divorce from makeup artist Annamarie Tendler was announced, the comedian was linked to Olivia.

The pair confirmed in September that they were expecting their first child together.

Now that the two have seemingly settled into parenthood, could a wedding be in store?
