Britney Spears knows how to treat herself.

The pop star's spending habits have been laid bare in new documents filed in her conservatorship, which show she raked in an impressive $19.9 million last year - and spent around $10 million, according to TMZ.

Her biggest cash splash? A whopping $152,000 on massages, grooming and nails.

Britney's two dogs were also very well taken care of, costing her $37,000 for the year.

The other major expenses were an $87,000 wardrobe bill and $30,000 for hair and makeup.

Those costs aside, Britney, 31, certainly loves a bargain. Given her total property and assets were listed at $69 million, it's kind of surprising she went on shopping sprees in US chain stories 99 Cents Plus and Pay 99 Cents or Less.

Of course, she wouldn't be Britney if she hadn't rung up a hefty fast food bill as well: among the receipts were charges from Domino's, McDonalds and In-N-Out Burger.

Despite her spending, the singer still isn't in control of her all her money. Her father Jamie Spears remains the conservator of her affairs, a role he took on in early 2008, following her very public breakdown.
