Jennifer Lopez is the Normal One

Britney Spears Runs the Show

"Each month, he will be allotted a certain amount of money for personal use - i.e., clothing, nightclubs, booze and day-to-day activities. Any big items - cars, or trips that go over allowance - need to be approved by Brit herself," said one source. "She acknowledges she has made a great deal of money. However, she is trying to show Kevin that he needs to be responsible and curb his out-of-control spending habits."

Meanwhile, a source at the Four Seasons Hotel in Maui told us the two are still not getting along: "I was in the elevator with Britney, and she was screaming at K-Fed on her cellphone that she had waited in the suite all day for him to call and had been trying to reach him and couldn't sit in there any longer."

Putting on Boxers 101 with Kevin Federline

"I'm pregnant!" revealed the 24 year-old pop star to another woman in the spa at Maui's Four Seasons Hotel where Britney, Kevin and their baby son are staying.

Federline, 27, also delivered the bombshell baby news to a friend, who told Star: "Kevin said, 'Britney's pregnant again,' and when I expressed surprise he said, 'Yeah, it shocked the sh-- out of me too.'"

Before they flew March 1 to Maui — where they're staying in the $12,000-a-night Presidential suite — Britney and Kevin looked like they were headed for a split. Kevin's broken promise to spend Valentine's Day with Britney prompted her to take baby Sean and jet off to Hawaii, leaving Kevin at home alone in Los Angeles.
