According to a Bahamian police report taken in February after his son Jett's death last year, Travolta acknowledged in his own words that "Jett suffered from a seizure disorder and was autistic." That's a big no-no in Scientology.

An alleged extortion attempt against John Travolta, the Scientology-believing Hairspray star whose teenage son Jett died January 2 in the Bahamas, is drawing a wider investigation. The FBI is now looking into the case.

• Another headache for John Travolta and Kelly Preston: A politician in the Bahamas may have been part of a plot to extort money from the couple following the death of Jett Travolta. [OK!]

Lawyers for John Travolta and Kelly Preston claim officials in the Bahamas tried to extort millions from the celebrity couple with "false claims" about the tragic but controversial death of their teenage son Jett.

Has anything the celebrity family of Jett Travolta said about the teenager been the unvarnished truth? If so, we missed it. Even the publicity photos of Jett they sent out after his death are Photoshopped.
