Justin's going to be one busy little Bieber on Feb. 9.
"Baby" singer Justin Bieber will do double duty on "Saturday Night Live" for its Feb. 9 episode, serving as both host and musical guest, NBC said Wednesday.
Bieber, who's currently thrilling tweeners everywhere on his Believe World Tour, has appeared on the late-night show in the past, serving as musical guest in April 2010 and appearing in a skit opposite "SNL" alum Dana Carvey's Church Lady character in a February 2011 episode.
"SNL" returns from hiatus on Jan. 19, with "The Hunger Games" star Jennifer Lawrence hosting and the Lumineers serving as musical guest.
