Break a leg!

The messy professional break-up between hot-shot personal-injury lawyers Ross Cellino and Steve Barnes is moving from the courthouse to the playhouse, dramatized in a stage show playing next month in Brooklyn.

“Cellino v. Barnes” will hit the stage Aug. 3 at The Bell House in Gowanus, with the respective roles filled by co-creators Michael Breen and David Rafailedes.

The show, which already has had a sold-out run at the borough’s Union Hall, is a retelling of the rise and fall of the professional bond between the legal eagles, known for their inescapable TV spots featuring the earworm “Don’t wait, call 8” jingle.

The union hit the skids in 2017, when Cellino filed suit against Barnes to dissolve the firm over a slew of squabbles.
