Another day, another shot of Justin Bieber showing off his hard-earned abs.

Justin and Kendall Jenner -- the new faces of Calvin Klein Underwear, and Calvin Klein Jeans, respectively -- attended a Calvin Klein Jeans music event in Hong Kong on Thursday, where the "Baby" singer especially wasn't shy about putting the goods on display.

Not to be outdone, Kendall also put her trim waist on display -- though more subtly -- rocking a simple grey shirt she tied up, with a sassy leather skirt.

However, the 19-year-old supermodel was definitely not as subtle about repping her Calvin Klein undies on Instagram on Thursday, when she gave her followers a super close-up look at her slim stomach.

"Hong Kong with @calvinklein #MyCalvins," Kendall wrote.
