Rihanna is taking names and numbers to court.

The pop star has filed a lawsuit against her former accountants, accusing them of mismanaging her money over a five year period.

In the lawsuit filed this week in Manhattan federal court, Rihanna and her tour company, Tourihanna, single out the accountancy firm Berdon LLP and former employees Michael Mitnick and Peter Gounis.

The petition accuses the firm and the accountants of costing Rihanna millions between 2005 and 2010. It claims the firm failed to properly reconcile costs and revenues but still pocketed millions in commissions from Rihanna’s 2010 “Last Girl On Earth Tour.”

Rihanna says Berdon also failed to monitor her unpaid song royalties of her chart-topping hits and mishandled her foreign and domestic taxes. The firm has yet to respond to the lawsuit.

Rihanna will be featured in the August issues Harper’s Bazaar Magazine. Check out all the photos and show details below:

Rihanna‘s top fan-site reports the name of Sky Living’s brand new fashion show starring Rihanna, Henry Holland, Nicola Roberts and uber cool stylist Lysa Cooper is: Styled To Rock.

Stylist Lysa Cooper completes line-up on the new fashion show. Sky Living proudly confirms the final co-host who will complete the trio of mentors in Styled To Rock, the ambitious and much-anticipated new fashion series, executive-produced by style icon Rihanna.

With the panel of mentors personally hand-picked by Rihanna herself, Lysa Cooper has styled some of the superstar’s most striking and most talked about outfits and has worked closely with her for numerous years.

Lysa joins fashion designer Henry Holland and Girls Aloud’s Nicola Roberts, who created her own Dainty Doll make-up range, to co-host Styled To Rock, the new fashion project premiering this Summer exclusively on Sky Living.

Styled To Rock will celebrate the extraordinary talent and creativity in the British fashion scene, and search for the next generation of raw, undiscovered fashion designers. Over ten weeks twelve unknown designers personally selected by Rihanna, will be challenged by the mentors to create outfits for a string of A-list music artists to wear for a variety of occasions, including stage, shoots, high-profile events and more.

The show will ultimately recognise the increasing influence popstars have on mainstream fashion trends and provide an enviable springboard for the aspiring designer’s future fashion career.

Sky customers will be able to enjoy the series exclusively on Sky Living HD later this summer. It will also be available on the move and on demand with Sky Go.
