Lady Gaga's ex-mentor sued by lawyers

Lady Gaga's former mentor Rob Fusari has been hit with a lawsuit from his attorneys for allegedly failing to pay his legal fees.

Lawyers from Meloni & McCaffrey claim they represented the music producer in his battle against the Poker Face star but were dropped shortly before Fusari and Gaga reached a settlement.

In legal papers filed in Manhattan and obtained by the New York Post, Fusari is accused of paying just $15,000 of his $47,000 bill.

Fusari sued Gaga for $30 million last year (10), alleging he came up with her stage name and co-wrote her early hits. The singer fired back with a countersuit, claiming he forced her into an "unlawful arrangement".

The two songwriters, who were said to have once dated, settled the matter in September last year (10).
