Using shots of British actress Natasha Bassett portraying Spears as a red carpet darling and onstage performer, the trailer gives a clip of Spears' infamous head-shaving incident.

"I’m not going to say I was fun, 'cause I wasn’t," Bassett says in a southern accent as Spears. "Everything’s just kind of this blur, you know? Until you hit rock bottom."

The trailer offers glimpses of the movie's interpretation of Spears' 2004 marriage to former backup dancer Kevin Federline and what looks like a re-enactment of a 2008 MTV documentary about the singer.

"I wanna be strong for my fans," a voice-over says. "They're what keeps me going."

Spears' publicist told Entertainment Weekly in August 2016 when the movie was first announced that the singer would not be involved in the film "in any way, shape or form… nor does it have her blessing."

"Britney Ever After" airs Feb. 18. at 8 p.m. on Lifetime. Watch the trailer below.
