'Britney Ever After' trailer shows Spears character shaving her head, getting married

Jan. 24 (UPI) -- Lifetime has released a trailer for its upcoming television movie Britney Ever After.

"You know her name, but do you know her story? #BritneyEverAfter premieres, February 18th," the cable network tweeted Monday, along with the 30-second video.

Monday's clip showed Natasha Bassett as Grammy winner Britney Spears performing on stage in front of adoring crowds and happily getting married, but it also offered a glimpse of a darker period of her life when she suffered from personal and psychological issues, and shaved her head bald.

The cast for the TV movie includes Nathan Keyes as Justin Timberlake, Clayton Chitty as Kevin Federline, Nicole Oliver as Lynne Spears and Matthew Harrison as Jamie Spears.
