What a protective brother!
Harry Styles may take his role as one of the world's most famous pop stars seriously… but that doesn't mean he's forgotten where he came from.
While performing with his One Direction bandmates at the Apple Music Festival in London on Tuesday night, Harry took a break from his set list to let his audience know that his older sister Gemma Styles was actually on a date at their very concert!
In fact, he even warned his big sis to behave herself in front of him! LOLz!!!
Ch-ch-check out Harry & Co.'s hilarious concert interruption (below)!!!
