It’s not every day that two famous best friends strip down to their underwear for a photoshoot on a major brand’s Instagram account, but that’s exactly what happened when Pete Davidson and Machine Gun Kelly took over Calvin Klein’s profile.

Here’s everything that went down during the spicy Instagram Live and how fans reacted.

On December 6th, social media users were shocked to see a photo of Pete Davidson’s face as the profile picture for Calvin Klein’s Instagram account.

The Saturday Night Live star wore a navy blue Calvin Klein cap in the image, which appears to be the same hat he wore in paparazzi photos holding hands with Kim Kardashian West.

The photos were published on November 18th, just two days after Davidson’s 28th birthday.

Davidson posted a mirror selfie to Calvin Klein’s Instagram grid, showing off painted fingernails and a white Calvin Klein T-shirt while flashing a peace sign.

He captioned the picture, “I got Instagram.”

The SNL star also removed all the accounts Calvin Klein was previously following, leaving only one: Davidson’s best friend, musician Machine Gun Kelly.

The same day, Machine Gun Kelly posted an Instagram Story tagging the fashion brand’s account, asking them if they were free at 5pm PST.

Fans eagerly tuned in to watch him go live with Davidson on Calvin Klein’s account.

The two friends sat on a white couch together with snacks and beverages on a coffee table in front of them.

They took turns pulling down their pants and doing a pretend photoshoot for Calvin Klein, showing off how they would pose.

Besides their spicy underwear shots, the two stars also got a little racy during their conversation.

“Nice stuff, by the way,” Davidson told his friend, referring to MGK’s underwear-clad genitalia.

“I get it now.

Good for you.

Good for you, dog.”

Davidson went on to describe his own manhood, stating that he’s “a grower for sure” and that it’s “actually the same small and hard.”

Acknowledging the camera, Davidson added, “I hope everyone’s horny at home.

We really brought the horniness.

We bring the horniness.”

After finishing their Instagram Live, Davidson and Kelly posted a photo of themselves peering into the camera on Calvin Klein’s Instagram grid with the caption, “did we nail it or did we nail it.”

MGK commented from his account, asking if they should remake Zoolander, while his new nail polish brand, UN/DN LAQR, commented, “💅’d it.”

Fans couldn’t get enough of the collaboration between the fashion brand and the two famous pals.

One Instagram user commented, “this will break Instagram,” while another implored, “please give us more content we literally are begging of you for a real shoot even though this was pure gold 🔥.”

One fan wrote, “thank god thank calvin thank klein,” and another commented, “give me undie photos or give me death.”

It’s clear that Davidson and Machine Gun Kelly’s steamy photoshoot was a hit among fans, and it remains to be seen if they’ll partner up with Calvin Klein again in the future.
