Ke$ha responds to ex-manager's $14M lawsuit

EXCLUSIVE: Singer says DAS acted as unlicensed agent

Pop star Ke$ha has dropped a particularly powerful legal bomb on a former manager who is suing her for $14 million in allegedly unpaid commissions.

In a move that will not be a surprise to lawyers familiar with talent-management disputes, the "Tik Tok" songstress is asking the California Labor Commissioner to declare her contract with DAS Communications void because it acted as an unlicensed talent agent while representing her. That's a big no-no in California, where only registered (and regulated) agents can "procure" work for clients.

Ke$ha (real name: Kesha Rose Sebert) was sued in New York in May for allegedly breaching a 2006 deal to pay New York-based DAS and principal David Sonenberg 20% of her music earnings. The singer later left DAS and hired RCA/Jive Record Group to represent her, according to the lawsuit. At issue is whether DAS is entitled to commissions from Ke$ha's lucrative deal with Warner Bros. Records, among other things.

The singer fired back at the lawsuit in August with a motion to dismiss the case, arguing that she was well within her rights to fire the management company. And now she is moving the fight to California, where she is alleging many acts of "procurement" for her work, including singing engagements, songwriting gigs and even performing at house parties
