Featuring what UPN bills as "exclusive, never-before-seen private home videos" of their "personal love story," the six-episode series is scheduled to premiere later this year. It picks up shortly after the pair met in Los Angeles and headed to Europe on tour, where Federline performed as a backup dancer for Spears.
UPN is also shooting new footage and commentary with the couple, who wed in September. It was the second marriage in nine months for Spears, who married childhood friend Jason Alexander in a surprise wedding in Las Vegas in January. That marriage was annulled 55 hours later.
Last week, the 23-year-old pop singer lashed out at tabloid magazines for reporting that she's pregnant and that the marriage is on the rocks.
"I feel that last year the tabloids ran my life," Spears said Tuesday, in commenting on her new series, "and I am really excited about showing my fans what really happened rather than all the stories, which have been misconstrued by journalists in the past."
Said Dawn Ostroff, president of UPN: "Now, for the first time, their millions of fans will get to see and hear the couple's real story on UPN as told directly by them."
