Tina and Justin! Oh My!! (Saturday Night Live)

Two huge stars are dropping in on "Saturday Night Live" this weekend. Former "SNL" player and current "30 Rock" actress Tina Fey will be there as well as teen pop sensation Justin Bieber. Fey will be the hostess while Bieber plays his music -- but the actress thinks the 16-year-old has potential. She tells MTV.com, quote, "I met him at the Kids' Choice Awards. He's a nice young man and I'm looking forward to hopefully doing a sketch with him." Fey also says she'll "attempt" her popular election-year Sarah Palin impression.
