Britney Spears squandered more half of her $100 million fortune.

According to New Of The World, a source claims that the troubled pop star has spent $60 million of her wealth in just three years.

"There are massive holes in Britney's finances, according to Jamie. He can't believe it," the source says.

Jamie had apparently learned of the big hole when he was made conservatorship of the estate and well-being of his daughter.

Britney has been contesting the appointment since her release from the psychiatric ward in the UCLA Hospital.

Meanwhile, the father and daughter duo spent the weekend with a quiet dinner. The two, along with their other companions, have so far been cordial to one another.
