You'll Never Guess Who Justin Bieber's Suprise Duet is With!

The lovable Canadian native Justin Bieber returned home Wednesday evening for a very special performance that has won over our hearts. Yeah we didn't know Justin could make us fall even more in love with him, but he has.

During his "Home for the Holidays" concert in Toronto, the biebz shocked the audience by bringing on stage his four year old little sister to sing with him.

Together, his sister Jazmyn joined him in singing some of his most popular hits including "baby."

The crowd went wild and was blown away by how cute the two were together. Justin's parents and grandparents were in attendance at the concert!
