Charlie Sheen spent more than $500,000 on escorts and drugs in the six months before he checked into rehab, RadarOnline.com is exclusively reporting.

The troubled Two And A Half Men star was said to have consumed mountains of cocaine and other drugs as he partied uncontrollably, according to sources within Sheen's inner circle.

"He spent a fortune... his preference is to smoke the cocaine," a close friend told RadarOnline.com.

A fourth adult film actress who partied with Charlie Sheen before he was taken by ambulance to the hospital has been identified as Shyla Jennings, RadarOnline.com has exclusively learned.

Jennings, a brunette from Texas, was named in court as the victim of a kidnapping plot orchestrated by reality TV vixen Tila Tequila.

Tila has denied any wrongdoing.

Tila Tequila is being sued for causing a Los Angeles photographer "emotional and physical distress" and "humiliation", RadarOnline.com has exclusively learned.

EXCLUSIVE DOCUMENTS: Read Garry Sun's Lawsuit Against Tila Tequila

The former reality TV vixen was granted a three-year restraining order against paparazzo Garry Sun in November.

But in a cross-complaint filed in a Los Angeles court, Sun has ratcheted up his bizarre claims that Tila kidnapped his ex-girlfriend, Shyla Jennings.

"Jennings told Sun that within five minutes, four men walked into her house and told her that she would be going 'somewhere' with Tila Tequila," the photographer's declaration says.

A former employee of Tila Tequila who is entangled in a legal battle filled with wild accusations has produced a romantic birthday card that he says she sent to him. If legitimate, the card would prove Garry Sun’s claims that he was romantically involved with Tila, which would make their ongoing legal battle even more bizarre.

Tila has denied being in a romantic relationship with Sun, a former employee. Sun accused Tila of trying to kidnap his girlfriend. He attempted to file a restraining order against her but it has not been signed off by a judge. Tila then was granted a restraining order against Sun.

“The picture of the angel in front of this card, was that little girl in Texas who layed [sic] dreaming of the day she would find someone like you,” the card reads inside. Sun says Tila wrote those words. The card, obtained exclusively by RadarOnline.com, is dated June 22, 2010.

Tila Tequila was granted a restraining order against her kidnapping accuser, Garry Sun, on Friday by the Los Angeles Superior Court and RadarOnline.com has the documents.

“I hope that he will never work in this town again so that he won’t be able to do this to other celebrities or anyone else for that matter!”

As RadarOnline.com previously reported, Sun filed a TRO against Tila on Tuesday after accusing her of kidnapping his girlfriend, Shyla Jennings, from her Texas home earlier this month.
