In the finale, titled "Veil of Secrecy," Spears, 23, and Federline, 27, reveal how they kept the secret of their surprise wedding ceremony last September in Studio City, Calif. Even closest friends and family were kept in the dark.
As PEOPLE reported at the time, some 20 friends and family members –including Spears's mother, Lynne, and sister, Jamie Lynn – attended the surprise wedding. Britney wore a white dress and Kevin a black tuxedo as the couple exchanged vows.
Added Spears: "It was perfect."
Since the show's May 17 debut, TV critics have given it mixed reviews. "One sure thing about Britney Spears's new reality TV show: There's no danger of anyone ever dumbing it down," judged The Washington Post.
Then again, the New York Post (having given the premiere three out of four stars) crowed, "Finally, a reality series that doesn't gloss over the dross. ... Who would have thought it would take bubbly, bubble-gum Britney Spears to bring us the first hint of reality in a reality show since The Osbournes?"
As for ratings, Chaotic fell to a season-low of 2.5 million viewers for the week that ended June 5, putting it in 92nd place.
