PHOTOS: LaToya Jackson... Also a Heath Ledger Fan?

LaToya Jackson has been very busy lately with interviews about Michael Jackson, but on Tuesday she took a break to attend the UK film premiere of The Imaginarium of Doctor Parnassus at Leicester Square in London. The film was Heath Ledger's final work before his death and a man who has the ability to control other people's imaginations. Anyone have any guesses as to why LaToya would be there?
