JUSTIN BIEBER and his 3-year-old sister, JAZZY, did an adorable duet during his “Home For The Holidays” concert special in Toronto, Canada.

The “Baby” singer called his tow-headed younger sibling onstage, and Jazzy dimpled her way through a duet with her brother singing…what else…”Baby, baby, baby….oooh!”

Some Beliebers in the audience even broke into tears at the tender way Justin held his sister and talked her through a question-and-answer dialogue before segueing into song….

Justin came home earlier to perform the acoustic version of songs from his holiday album, “Under The Mistletoe,” to the screams of his adoring fans.

“The holidays are a very special time of the year for me, and I’m looking forward to coming home and ringing them in with my friends and family,”

Justin declared to an audience of rabid Beliebers, which included his parents, grandparents and childhood friends.
