2:00 PM PT -- George Lopez's team has responded to the claims, placing the blame at the feet of Eagle Mountain Casino in a statement to TMZ, saying, "It’s the venue or casino’s job to provide a good experience for both the artist and the fans, but the casino failed in this regard. The audience was overserved and unruly, and the casino staff was unable to provide a safe and enjoyable experience for the artist and guests."

"George’s personal security team worked with the venue security staff to maintain order, ensure safety, and eject disruptive individuals. Unfortunately, the casino security team was not adequate to accomplish this task. George is not obligated to perform in an unsafe environment. He feels badly that those who came to see the show were unable to do so as a result.”

George Lopez is catching some flak online for allegedly walking out of his most recent gig early ... and not just from pissed-off fans, but from the venue too!

The comedian had a gig at Eagle Mountain Casino in Porterville, CA Friday night -- a rescheduled gig after he canceled last month -- and, social media users are sharing videos online claiming Lopez bailed on the show after some heckling.

Fans didn't catch the alleged heckling, it seems ... but, people online narrate the aftermath of the apparent walk-out -- saying he left the show. The clips mainly show people milling about confused and angry as they head to the exits.

Eagle Mountain took to their own Facebook page to address the incident ... and, we gotta say they seem to be taking some shots at GL -- saying right off the bat they feel he "let down his fans and sold out audience" by ending the show half an hour earlier.

They say hecklers got to Lopez, who apparently just bailed despite the casino saying it had a plan in place for its security team to take care of offending parties.

Eagle Mountain adds they've helped George reschedule the show after he canceled last month -- due to a medical emergency, they add ... going above and beyond to provide Lopez with first-class service -- so, it's easy to see why they put out their scathing post.

They end the statement by saying they are as disappointed and shocked as the fans who didn't get the full show they came for ... and will release a more detailed statement Monday.

We've reached out to George Lopez's team and the casino for further clarification ... so far, no word back.
