*According to TMZ, Alejandra Jackson — the houseguest who just wouldn’t leave — has agreed to vacate the Jackson family compound — and sources say a tell-all book deal is in the offing.

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 TMZ the Estate is not paying Alejandra anything or offering her any housing — this was Alejandra’s decision — and it’s a clear sign a book deal has been closed.
