Pop star Justin Bieber's party on Friday night was crowded with naked women, who received more than $10,000 in combined cash Bieber tipped.

According to TMZ.com, sources and strippers in the party said Bieber had a "bunch" of one dollar bills, which he made it rain all night during a party that was attended by Snoop, Floyd Mayweather and Chris Brown.

"As for booze and weed ... we're told there were 3 open bars and plenty of kush to go around," TMZ reported. "Some non-stripper girls who were full dressed, felt self-conscious so they started to stripp down too."

The 100-crowded-party at Bieber's Calabasas home was so disturbing that one of his neighbors called the police, who had to came out for three times last of them at 5:30 am with no success on stopping the noise.

"The cops will write a full report and decide whether to send it on the L.A. County DA for possible prosecution," TMZ informed.

The partygoers had to sign at the door a confidentiality agreement obstructing them to take pictures, tweet, post or talk about the party. The violation of the agreement could cost them $3 million.
