"I went to past-life regression therapy and I'm pretty sure I was JFK (John F. Kennedy). He said I was a really successful American man who was assassinated. So who else could it be?" Singer Ke$Ha believes in reincarnation.

Ke$ha things spending a lot of cash is "gross" because she was once so poor she had to sell her clothes to eat. The star insists she has no plans to live lavishly because the memories of being poor are still raw.

She told STV.com, "I'm the same person I was when I was selling clothes to buy a taco for dinner."
