Anne couldn't hide her pride as she posed with her son, who had walked off with a Brit Award earlier in the evening.
The band also took to the stage to perform their Comic Relief single 'One Way Or Another (Teenage Kicks)', which saw them running around on a giant pinball machine.

After a heavy night of partying, Harry then popped up on BFF Nick Grimshaw's Radio One Breakfast Show on Thursday morning.
The boybander reckoned he was feeling 'fresh' after his big night. We'll bet.
