Steve Wynn and porn producer Joe Francis face off before jurors in Los Angeles this week, with the casino mogul denying that he threatened to kill the “Girls Gone Wild” founder and saying the accusation is threatening his upscale casinos, the Associated Press reports.

Wynn is suing Francis for slander, the latest legal fight in ongoing battles between the two men that include gambling debt that Francis racked up in one of Wynn Resorts Ltd.’s casinos.

Jurors on Tuesday listened to wildly varying accounts of whether Wynn threatened to hit Francis over the head with a shovel and have him buried in the desert, with the soft-porn producer insisting he heard about the threats from record executive Quincy Jones. Francis testified that Jones told him Wynn made the threats in conversations and emails, but Wynn denies it.
