According to the magazine, Spears and Federline not agreeing on the terms of a prenuptial agreement is what held up the couple from procuring a marriage license.
"This is all ludicrous," a spokesperson for Spears told Us. "They are happily married, and I have no reason to believe otherwise."
Spears and Federline celebrated what most thought was their wedding day late Saturday night/Sunday morning at the Studio City, California, home of wedding planners Alyson and Jeff Fox. Approximately twenty-five close friends and family members, including Spears' mother and sister, were in attendance.
Spears and Federline may be planning another wedding, or simply the paperwork: according to California state law, a couple may certify its nuptials retroactively.
