The 19-year-old was criticized for turning up late to his sell-out London show and managed to get himself into a tussle with a cameraman during his stay in the capital, reported Showbizspy.
"You live life and it's hard to grow up in front of a camera. You learn as you get older to take moments for yourself, step away from the camera, re-inspire yourself as an artist, rejuvenate and refresh," Aguilera said.
The 32-year-old also advised the Canadian singer to be true to himself and ignore outside influences.
