Watch the First Trailer for Lifetime's Britney Spears Movie

Lifetime is finally ready to show a piece of its upcoming Britney Spears movie.

The cabler unveiled the first trailer for the film, titled Britney Ever After, on Monday, but it's hardly a happy look at the singer's time in the spotlight.

Sure, the footage shows Natasha Bassett as Spears dancing, singing and even embracing husband Kevin Federline at their wedding. But the trailer also shows Spears as she hits what she calls "rock bottom," including famed moments such as when Spears shaved her head and when she attacked paparazzi with an umbrella. 

"I'm not going to say I'm fine 'cuz I wasn't," Bassett's Spears says in the video.

This is Lifetime's latest in a long line of musician-centered biopics, including the network's 2015 Whitney Houston film. Next up is a two-hour movie centered on the final years of Michael Jackson.

Check out the full trailer above. Britney Ever After premieres Feb. 18 on Lifetime.
