Jennifer Lopez is being blasted by Howie Mandel as a less than an ideal Hollywood neighbor.

Radar Online reports Mandel claims the "Jenny from the Block" singer recently hosted a Medieval Times-themed party, more or less taking over the entire street without much consideration for anyone else.

"I live about three doors, four doors down from J.Lo," Radar reports Mandel recently said on the "Allegedly with Theo Von & Matthew Cole Weiss" podcast. "So I live in a cul-de-sac. I walk out one day and go to the bottom of the driveway and my cul-de-sac is filled with knights in shining armor on horses. It's Medieval Times."

Making matters even worse, Mandel claims all the horses were allowed to freely relieve themselves, in many instances, right in front of his house.

"They have jousting sticks," he said. "And all the horses are sh*tting. There's so much horse sh*t. There's knights and damsels. I go 'What the f*ck? What is this?' And they go J. Lo is having a party and J. Lo ordered Medieval Times at her house."

Mandel didn't seem too worried that all his complaining could ultimately cost him an invite to J. Lo's next big house party.

"I was never invited the first time," he quipped.

Medieval celebrations aside, it's a good time to be the 46-year-old Lopez, soon slated to commence her "All That I Have" Las Vegas residency tour at Planet Hollywood Hotel & Casino, as well as a gig as a judge on the final season of "American Idol" alongside Keith Urban and Harry Connick, Jr.

"I'm super excited about it," Lopez told E! Online of the six-month Vegas tour that officially kicks off in mid-January. "I love performing. I really feel like I'm gonna get to create a really special show, a special experience."
