With her Vegas debut fast approaching, E! will air a 90-minute documentary about Britney Spears called I Am Britney Jean, following her as she preps for the two-year Planet Hollywood residency. Britney's Britney: Piece of Me hits Vegas on December 27, while the doc hits cable on December 22 — and the latter might give you a good idea if you'll be buying tickets to see the former.
