Alejandra Jackson to Move Out -- Book Deal Imminent

Alejandra Jackson -- the houseguest who just wouldn't leave -- has agreed to vacate the Jackson family compound -- and sources tell TMZ a tell-all book deal is now a done deal.


Alejandra -- who has 5 kids via two of Michael Jackson's brothers, Randy and Jermaine -- has been a squatter in the Encino compound for months -- and was probably going to be evicted next week after a court hearing, but she has informed the Michael Jackson Estate she will be moving out by April 14.

The Estate had offered Alejandra a condo, provided she sign a confidentiality agreement, but she refused.  Sources tell us the Estate is not paying Alejandra a penny or offering her any housing -- this was Alejandra's decision -- and we're told it's a clear sign a book deal has been closed.
