Charlie Sheen spent $790,000 on cars in the past month, including two for his porn star friends.

The 'Two and a Half Men' star - who was hospitalised following a 36 hour- hour drink-and-drug binge with adult film stars last month - is also reported to have bought vehicles for his soon-to-be ex-wife Brooke Mueller and his new girlfriend Natalie Kenly.

According to a source, Charlie bought a Bentley worth $320,000 and a Porsche Turbo costing $150,000 for two adult film star friends.

He also purchased a $160,000 Mercedes-Benz S63 for his new 24-year-old girlfriend and splashed out another $160,000 on a Mercedes-Benz CL 600 for Brooke, with whom he has 23-month-old twins, Bob and Max.

This is not the first time Charlie - who earns $2 million an episode for his TV show 'Two and a Half Men' - has splashed the cash for his porn star pals.

Kacey Jordan had sex with Charlie the night he was hospitalised and recently spoke about the aftermath of their wild night, saying: "I had to go, it was already the afternoon the following day he was still going on drugs...

"I called my driver and I was like, 'You need to pick me up now'... he grabbed the cheque book and says 'I'm going to give you $25,000...' and he says 'You know what, I like you, I'm going to give you $30,000.' "

Friends have also claimed the actor dreams of creating a 'porn family' and wants to buy a house close to his own where adult film stars can live.

Charlie - who also has daughters, Sam, six, and Lola, five, with ex-wife Denise Richards, as well as a grown up daughter Cassandra from a previous relationship - has also offered to by homes for both his former spouses.
