Justin Bieber may have been born to be a Calvin Klein model. The Canadian pop star recently teased fans by giving them a glimpse of his Calvin Klein-labeled underwear at a recent event in Hong Kong that was organized by the clothing brand.

“It looks like I ripped my pants,” Bieber teased a screaming crowd of teens at Hong Kong's Kai Tak Cruise Terminal on Thursday, wrote Hollywood Life. “Do you guys mind?” Bieber asked his fans, who were ready to see their favorite singer undressed. “Should I just take them off?” the singer teased further.

Though the audience seemed willing to see Bieber in his undies, the singer kept his pants on. The 21-year-old, who appears in Calvin Klein ads, then gave a surprise performance, singing his hits like "Boyfriend" and "Beauty and a Beat."

Meanwhile, model Kendall Jenner did not shy away from posting a selfie on Instagram that shows her wearing Calvin Klein underwear. Just like Bieber, Jenner also endorses the brand.

"Modeling for Calvin Klein Jeans is really a dream come true," Kendall said in a statement in March, when her link to the brand was announced. "I've grown up wearing the brand and seeing the iconic advertising in magazines and on billboards featuring some of the world's top supermodels. To now be a part of that legacy is truly an honor," she added.

Jenner also was in Hong Kong to promote the brand. The 19-year-old attended the same promotional event in a gray, full-sleeve, cropped top and stylish, black leather miniskirt. Jenner joined Bieber and the two posed for photos. Bieber wore a plain white T-shirt and black denims. Check out the video here.
