Britney Spears rakes in '$13 million in one year'

Britney Spears reportedly made over $13 million last year (15).

The pop icon continues to rake in the cash, despite not releasing an album since 2013, due to the popularity of her Las Vegas residency, Britney: Piece of Me.

Following a very public meltdown in 2007, Britney’s assets were put under conservatorship of her father James Spears and her attorney, giving them control of her assets.

Legal documents posted by Britney’s conservatorship, and obtained by website TMZ break down what the singer earned and spent in 2015.

The website claims the star made $13,395,410.53 in 2015 alone. And despite paying taxes and various other expenses, her legal documents reportedly state she rounded off the year with a $51,141,000 fortune in earnings and property.

The final sum allowed for $8 million worth of expenditure throughout the year, with the website reporting the Womanizer singer spent $67,800 on massages, grooming and nails, and by comparison a rather conservative $62,813 on her wardrobe.

But it wasn't just Britney who reaped the benefits of her large income, a staggering $37,360 was reportedly spent on maintaining the lifestyle her pampered pets have become accustomed to. The 34-year-old is believed to have two dogs, a Teacup Yorkie and a Maltese.

Britney will no doubt continue to bring in the cash this year (16), with the Toxic star set to release her ninth studio album on 26 August (16). She’s already released the lead single, Make Me... which features guest vocals from rapper G-Eazy, and also unveiled her latest fragrance Private Show in June (16).

The blonde beauty’s perfume line has proved extremely lucrative over the years, with her first fragrance Curious, launched in 2004, earning $100 million in sales in just five weeks, before going on to become one of cosmetic house Elizabeth Arden's top selling products.
