WATCH: Shirtless Nick Bosa stars in Kim Kardashian-inspired campaign alongside Neymar Jr.

San Francisco 49ers defensive end Nick Bosa and Al Hilal striker Neymar Jr. became part of Kim Kardashian's shapewear brand as the reality television star moved to expand SKIMS.

Kardashian took a novel approach to her brand with one eye on adding men to her customer base. In an effort to do so, she teamed up with Bosa, Neymar Jr., and NBA star Shai Gilgeous-Alexander this week.

In the video, the athletes were seen posing shirtless and in the brand's innerwear. Neymar posed with a soccer ball and a green t-shirt. Shai, on the other hand, chose a green pair of boxers. Finally, Bosa wore a pair of grey boxers.

They introduced themselves and then promoted the brand.

Kim K was excited to introduce Neymar Jr., Nick Bosa, and Shai Gilgeous-Alexander as the faces of the brand. She said:

"To have an icon like Neymar Jr be the face of our launch campaign, along with NBA All-Star, Shai Gilgeous-Alexander and NFL’s top Defensive Player Nick Bosa, I think speaks volumes to the way SKIMS has evolved into becoming a brand that can provide comfort for all audiences, not just for women."

The $4 billion company will begin to sell men's boxers, briefs, undershirts, t-shirts, leggings, and tank tops.

DPOY candidate Nick Bosa says he forgot his routine after 49ers loss

The San Francisco 49ers will play against the Minnesota Vikings in Week 7 on Monday Night Football. The Niners will be keen on shrugging off the loss they suffered at the hands of the Cleveland Browns in Week 6.

The star pass rusher admitted that losing their Week 6 game made the routine following a loss feel unfamiliar.

"It’s been a long time since we lost,” Bosa told reporters.

“I actually forgot what the routine was when it comes to team meetings and all that stuff. It was tough, we kind of had to eat it for an extra day. We were kind of dreading coming in here for meetings."

Bosa is right, of course. The Niners have been winning and dominating in the NFL ever since Kyle Shanahan got his offense and defense on the right page. Christian McCaffrey's arrival has only worked to supercharge their offense.

While there was some doubt on McCaffrey's availability for Week 7 against Minnesota, the star running back will, in fact, take the field on Monday Night Football. Wide receiver Deebo Samuel, on the other hand, is likely to miss out.
