Justin Bieber Singing With Sister (Video)

Hi there, I'm Lauren Bradshaw. Check out this adorable video of Justin Bieber singing with his little sister in today's PopSugar Rush. Justin Bieber has performed with everyone from Usher . . . . . .to Mariah Carey . . . . . . but he had a very special guest at his Christmas show in Toronto last night. SISTER: Baby, baby, baby, oh JUSTIN: I thought you'd always be mine JUSTIN: Give it up for Jazmyn everybody. Justin is back in Canada to spend the holidays with his family, and he brought his three year old little sister Jazmyn up on stage to sing his hits "Baby" and "One Time." JUSTIN: "I'm going to tell you . . . SISTER: "One time . . . JUSTIN: "I'm gong to tell you . . ." SISTER: "Two times . . . " The performance was part of a concert special that airs tonight in Canada, but Justin was also spreading the cheer here in the states yesterday evening. JUSTIN: "Under the mistletoe with you, shorty with you, with you . . . " Justin performed for children at St. Anne's as part of Martina McBride's Home For the Holidays special on CBS, and that's not the only way the pop star is giving back. He also made a donation of $500,000 to the Children's Wish Foundation last night, giving the charity a very merry Christmas. JUSTIN: "You want to say bye to all the fans? Say bye everyone."
