Rick Ross Ex-Groundskeeper's a Liar I Never Pistol-Whipped Him

Rick Ross is attacking the groundskeeper who is suing him for allegedly pistol-whipping and beating him ... but this time, Ross is admittedly attacking with a gun ... a hired gun.
Ross has filed legal docs against Jonathan Zamudio, who sued Ross claiming the mogul got angry at him for throwing a party in his mansion and driving his cars. Zamudio says Ross locked him in a room, pistol-whipped him and brutalized him so bad he had to eat through a straw.
But Ross now says Zamudio is lying ... and claims he has proof. For starters, Ross notes Zamudio called 911 THREE HOURS after the alleged incident and never mentioned pistol-whipping or any injury for that matter. He also spoke clearly and calmly to the dispatcher.
