The six-episode series will feature "exclusive, never-before-seen private home videos they shot themselves during their courtship, engagement and wedding," according to a statement from the network.
Spears's Web site also has released more details, saying the show will give "viewers a rare glimpse inside the pair's relationship and life together. The footage begins shortly after Britney and Kevin first met in Los Angeles and headed off to Europe together on tour, leading up to and including their wedding day."
The show also will include new commentary from the couple designed to lead viewers through the action.
In a message on the network's site, Spears says, "From the day Kevin and I met, there have been constant rumors and inaccurate speculation about our lives together. … I am really excited about showing my fans what really happened."
