Nick Carter has been overwhelmed with emotion during the Backstreet Boys' performance in London.
The older brother of the late Aaron Carter, who was pronounced dead over the weekend, continued with his singing commitments with the legendary boy band.
They performed their latest and greatest hits at London's O2 Arena as part of their DNA Tour and fans went wild with the musical nostalgia.

However, the Backstreet Boys paused for a moment to acknowledge the profound loss of Aaron Carter.
Just after they performed 'No Place', Kevin Richardson told 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 recognise him. Nick’s little brother, Aaron Carter, passed away yesterday.

Howie Dorough added: "We’d like to dedicate this next song to our little brother Aaron Carter. You'll definitely be missed brother. May you rest in peace."
Photos of Aaron were splashed onto the big screen and Nick broke down in tears at the touching tribute.
The Backstreet Boys then launched into their song 'Breathe'.

"My heart is broken," he said.
"Even though my brother and I have had a complicated relationship, my love for him has never ever faded.
"I have always held on to the hope that he would somehow, someday want to walk a healthy path and eventually find the help that he so desperately needed."
Aaron Carter was found dead inside his California home on November 5. His cause of death is still being determined.
The 34-year-old's family said authorities are investigating the circumstances of his tragic passing.
