Justin Bieber Sings Rebecca Black's 'Friday,' Britney Spears' 'Baby One More Time' (Video)
Rebecca Black's "Friday" has been seen more than 67 million times on YouTube, and it seems that Justin Bieber might be among those viewers.
At a recent concert, the pop singer launched into a few bars of the song, which has received a slew of negative comments and turned 13-year-old Black -- a self-professed Bieber fan -- into an overnight celebrity.
Bieber also sang a few lines from Britney Spears' debut hit single, "Baby One More Time," before launching into his own similarly titled hit, "Baby."
On Wednesday, Paramount Home Entertainment announced that Bieber's concert-themed film Justin Bieber: Never Say Never, which recently passed Michael Jackson's This Is It to become the most successful concert-themed movie at the domestic box office, will be released on Blu-ray/DVD on May 13.
