Britney Spears is doing groundwork to get herself frozen after her death, hoping that she can be brought back to life, sources say.
The singer wants her body preserved in liquid nitrogen, in a process known as "cryogenic" freezing.
The 'Womanizer' plans to invest in a firm, The Alcor Life Extension Foundation, which specializes in the life expanding process.
The firm's aim, stated on it's website, reads: "Using ultra-cold temperature to preserve human life with the intent of restoring good health when technology becomes available to do so."
Spears apparently got interested in cryogenic freezing after she heard rumours that Walt Disney has been preserved similarly.
"Brit gets these obsessions and this is the latest. It started when someone told her Walt Disney had been preserved by cryogenics to be revived in the future," the Sun quoted Spears' pal, as saying.
The friend added: "That was a myth but it got her researching the foundation and she became convinced it was worth a shot.
"Brit found the whole thing so interesting she spent most of her Mother's Day trip to Disneyland researching the subject on the internet while a nanny took the boys round the park.
"She looked into having her ashes turned into diamonds after she is gone but settled on the chance of getting to live in the future."
However, Spears can make any huge investment only with her father Jamie's consent.
The source said: "Jamie is quite happy to let Brit have her little obsessions, especially when it means she's holed up on the internet safely or watching the Discovery Channel.
"And if she wants to invest her money in cryogenics that's fine, we're only talking 350,000 dollar tops. However, much more than that and he may change his mind."
