Bieber blitz: Justin reads Letterman's Top 10, may make 'SNL' cameo

Justin Bieber's pre-movie media onslaught continues this weekend. Friday (Feb. 4) he made his second appearance on "The Late Show with David Letterman" in a week, and there are reports that he'll pop up on "Saturday Night Live" as well.

The Bieb read the Top 10 list on Letterman's show Friday night, and the topic was one he knows well: "Reasons it's fun to be Justin Bieber." You can watch the full list above (and also see him sit in with the "Late Show" band on drums); here are a couple of our favorites:

9. I'm briefed each morning by the CIA.
7. When I'm sick, my doctor makes hilarious jokes about "Bieber fever."
5. At the barber shop, I can say "Give me the me."

It looks like Bieber is sticking around New York this weekend. The Hollywood Reporter says he'll make a "surprise appearance" on "Saturday Night Live" this weekend (although it's less of a surprise now). We're guessing it will be in a sketch, because we don't really see musical guest Linkin Park jamming with him.

Bieber's concert movie/biopic "Never Say Never" opens Friday. As if you needed reminding.
