London, UK - Nick Carter and the Backstreet Boys emotionally paid tribute to the late Aaron Carter during their London concert.

On Sunday evening, the pop stars, who are currently on a six-country tour overseas, honored the 34-year-old younger brother of Nick, who tragically passed away on Saturday.

As shown in a clip that was posted by the theater website and Twitter account All That Dazzles and has since circulated, Backstreet's Kevin Richardson paused midway through the group's concert at the O2 Arena to tell the crowd, "Tonight we got a little bit of heavy hearts because we lost one of our family members yesterday."

"We just wanted to find a moment in our show to recognize that Nick's little brother, Aaron Carter, passed away yesterday at 34 years old," the singer continued.
