Kesha's former managers want the lawsuit against her sorted before she runs out of cash, it has been reported.

The singer is being sued by her former managers at DAS Communications for up to fourteen million dollars. The company have urged a Manhattan District Court to expedite the singer before she runs out of money, the New York Post reports.

Ke$ha "is a very young and inexperienced artist whose 'star' may not continue to rise", court papers against the singer say.

"Although she has made an incredible amount of money in a very short period of time, in large part due to DAS' efforts on her behalf, she could just as easily lose money if not properly guided."

Ke$ha's 'Tik Tock' has become the biggest downloaded single of 2010, it has been revealed.
