David Arquette says he's gonna BRING THE PAIN when he returns to the wrestling ring to face RJ City next month -- and he's especially pissed because RJ's been disrespecting Betty White!!!
Arquette -- former WCW Heavyweight champ -- is battling Canadian wrestler RJ City to settle their nasty Twitter feud once and for all!!!
The two have been going after each other -- RJ called Arquette a "burnt out actor" and a "piece of sh*t." Now, they've set a date to rumble -- July 15 -- at the Oceanview Pavilion in California.
