MTV scores with Spears special

Documentary tripled the time period average

For the record -- Britney Spears' MTV special did pretty good Sunday night.

"Britney: For The Record" averaged 3.7 million total viewers at 10 p.m.

It also pulled in a 3.5 rating in the network's target demo of persons 12-34, tripling the time period average in that demo and all others.

The documentary, part of Spears' career relaunch, provided insight into pop princess' rough last few years and into her paparazzi-filled everyday life.
