Is Jennifer Lopez the new Paula Abdul? Let’s just hope she wears less jewelry (pills) now that she’s serving judgment on American Idol. One sign that JLO’s filling Paula and not Simon’s shoes: the love-fest between the singer and Ryan Seacrest is already in full swing — starting with the exclusive premiere of her new single On The Floor on Seacrest’s radio show. While the song’s pretty good, it’d be a hell-of-a-lot better without “On Air with Ryan Seacrest world premiere” edited in every 15 seconds. Barf.
