New York ? They may have had a bad romance, but now there’s an amicable professional split between Lady Gaga and a music producer who said she ditched him as both a collaborator and a boyfriend after he helped launch her career.

Court papers filed this week show the Grammy Award-winning “Bad Romance” singer and songwriter-producer Rob Fusari agreed to dismiss the lawsuits each filed against the other in March.

He’d sought $30.5 million, but it’s unclear whether they made any monetary deal. Lawyers for both sides and a Gaga spokesman didn’t immediately respond to phone and e-mail messages Friday.
