Former "Bachelorette" star Kasey Kahl is adamant ... the couple he brawled with inside a Fresno nightclub are just a couple of "Jersey Shore" wannabes bent on attaining their 15 minutes of fame.

Kahl's rep has released a NEW statement in the wake of an explosive police report, in which an allegedly intoxicated Kahl is accused of beating up a 25-year-old named Richard Chaney ... and smashing the dude's GF in the face at a Fresno nightclub this weekend.

Team Kahl says ... "As Kasey is in the public eye, it is not unlikely that we would not be surprised if these persons bent on attaining their 15 minutes of fame, while intoxicated and perhaps fueled by jealousy, will antagonize and attack stars such as Kasey in a 'Jersey Shore' type brawl given the opportunity."

He adds, "These persons wanted their 15 minutes, which they received, and now those 15 minutes are over."

Kiptyn Locke -- a contestant on "The Bachelorette" who jumped to the show "Bachelor Pad" -- just underwent 4 1/2 hours of emergency surgery to repair severely ruptured discs in his neck ... that were perilously compressing against his spine.

Neck injuries are no joke ... but we're told Locke -- who is currently dating former "Bachelor" contestant Tenley Molzahn (left) -- is expected to make a full recovery. It's unclear how Kiptyn injured himself.

Tenley says, "There are definitely angels involved in this emergency."

The bad blood between cast members on "Bachelor Pad" has spilled into real life ... so says one of the losers who claims Graham Bunn punched him in the face at a nightclub this week.

TMZ spoke with Justin Rego (aka Rated-R) -- who was eliminated from the reality show last month ... who says he was hanging out at the wrap party at a Hollywood nightclub Wednesday night when all hell broke loose.

According to Rego, two other members of the show -- Graham Bunn and Blake Julian -- had gotten into an argument ... and it started to become physical.

Rego says he went to break up the fight -- when Graham punched him in the nose ... and he started to bleed. Sources at the club tell us security rushed over to the scene and escorted Graham out of the building.

Justin tells us he does not plan on pressing charges -- but says he's still pretty pissed off at Graham. A rep for Graham tells TMZ, "It was nothing -- just boys being boys.”
