Justin Bieber's party lifestyle hasn't gone unnoticed in the recent months, with his home in Calabasas, LA., hosting huge extravaganzas.

But the latest one nearly ended in suspicious circumstances.

The 19 year-olds latest house party, in the early hours of Saturday morning (Dec 14th), saw a female attendee found unconscious.

TMZ reports, the 20 year-old female was found around 3am and an ambulant was dispatched but 15 minutes later it was called off.

The gossip site states the young partygoer regained consciousness and when learning an ambulance was on its way insisted it to be cancelled.

Despite been under the legal drinking age, alcohol was reportedly a factor in her passing out.

A source close to the 'Love Me' singer told Hollywoodlife.com "There was no issue, a call was made out of an abundance of caution, but the woman was given some food and liquids and was fine and went home."

Bieber's party have become infamous in the private gated Los Angeles community as he even makes guests sign a waiver stating they will not release any photos, videos or information about the evening's antics.

If anyone is to violate the gag order then the penalty is a hefty fine of $3 million.

Last month in November (15th), Justin threw one of his lively house parties which resulted in the police reportedly being called three times to the late night rave, which was attended by 100 partygoers, the noise proved to be too loud for the surrounding residents.

The 'Boyfriend' singer also boosts guests such as Snoop Lion, Floyd Mayweather and Chris Brown, but these frequent celebrations are leaving the surrounding residents very angry but it doesn't seem like Bieber is going to stop anytime soon.
