Remember the reports about David Arquette getting into a scuffle with Justin Bieber which resulted in the 43-year-old being kicked out of the singer's 21st birthday bash? Well, part of that story true. Arquette called into The Howard Stern Show this morning to explain what really went down in Sin City.

According to Page Six's initial report, the pop star wanted Arquette thrown out of his Vegas party after he caught wind that David was “talking about Bieber behind his back.”

The source said: “Justin heard what David had been saying, and threw him out of his suite with the help of a friend, because they didn’t have security up there. Somehow David managed to get back in and rushed at Bieber to take him out. There was a confrontation, then other people got in the way to separate them. David was thrown out again, this time for good.”

While speaking to Stern on Monday, Arquette insisted, "I didn't get in a fight and thrown out."

What really went down was the Biebs had just thrown his birthday bash (following the taping of his Comedy Central roast in L.A.) at David's new club in Las Vegas, Heart of Omnia, at Caesars Palace. After the shindig, David got into an elevator thinking he was going to a friend's afterparty and when he got off, was asked to put his cell phone in a pillow case.

"I'm thinking that's weird… but we do it and we go in and I'm not at my friend's party — I'm at Justin Bieber's party. So I'm crashing, right now I'm crashing," he admitted. "I don't think it's so bad because he just celebrated his birthday at [our club] and we know Scooter [Braun}

David said he went up to Justin to thank him for having his bash at Omnia "and he flicks me in the head with a bottle cap."

Naturally, Howard responded to that by calling Bieber "a little prick."

Arquette defended Justin, "He's not a little prick, I'm already crashing his party… I'm thinking it's a homeboy game," he explained. "[Justin] runs to the bathroom, I chase him and he's kind of giggling or whatever. I think we're being silly… silly fun. So I walk up and I start talking to his friends."

When the Biebs came out, David said he "popped him in the nuts" but "not hard… a little love tap… he actually giggles [it] off and everything is cool. Then this is where it got weird."

David noted he was wearing a fancy, custom-made suit that said "David Arquette" on the pinstripe, which costs about $8,000. The Scream star said he went to thank the pop star and that he would like to get him a similar suit that says "Justin Bieber" in the pinstripe

.

"At that point, I think he thought I was trying to sell him a suit or something, and he got awkward,"Arquette recalled. "Maybe I'm too aggressive. I was a little saucy I wasn't too bad… I think I offended him. So his friends were like, 'I want you to leave now.'"

So David was escorted out — but not before he got in the last word, which he sheepishly admitted was a "shameful moment" for him.

"I walk out, I'm getting kicked out of this place, and I do a little smooth move and I ditch the security and stuff and I come right back up," he continued. "I should never do this, I'm never going to pull this card again, but I did. And I said, 'Yo bro, I know you're kicking me out. I didn't mean to offend you, my sister just won the Oscar so don't get too big in your britches,'" he confessed. "I know, it's a shameful thing to say. I didn't win the Oscar." (In case you don't know, Patricia Arquette won Best Supporting Actress Oscar for her performance in Boyhood.)

"The reason I'm telling this story is because the stories said I went back to fight him, and I don't fight and nobody should," he concluded. "That's it
