U-KISS snapped a photo with the Backstreet Boys.

The boys were invited to perform at the 'Twin Towers @ Live 2013' concert in Malaysia. They were on the same stage as American artists such as the Backstreet Boys and Demi Lovato. Because they shared the same stage, they had an opportunity to snap a photo with the legendary group.

The official U-KISS Twitter account tweeted the above photo and wrote, "With Backstreet Boys in Malaysia! I remember working hard on 'As Long As You Love Me' before debuting~ It was a great time we got to spend with people we respect! We'll become a U-KISS that will never forget how it all began!!^^".

Previously, the Backstreet Boys had also taken photos with Super Junior-M in China as well.
