VH1’s original movie “Crazy Sexy Cool: The TLC Story” averaged 4.5 million viewers Monday night to rank as the network’s highest-rated telecast in over five years.

The movie scored a 2.9 rating with the advertiser-preferred adults 18-49 demographic, making it the top performing cable original movie of the year and VH1’s highest-rated original movie ever.

It also ranked as the most talked about program on Twitter Monday night with 1.9 million tweets, according to SocialGuide, four times more than the next-closest program, “Monday Night Football.”

“Crazy Sexy Cool” follows the female R&B group from their humble beginnings in Atlanta through their ’90s heyday — “No Scrubs” was one of their hits — and the death of member Lisa “Left Eye” Lopes.

VH1 will re-air the movie on Oct. 27 at 8 p.m.
