Why do celebrities always need to write a book?

Like memoirs and autobiographies. Not that I'm saying they don't have a right to, but why do so many feel like they should? Because a lot of times they end up putting stuff in their books that stirs up drama with people they know/knew like family members, ex lovers, or even co-stars. I get that everyone has gone through problems, disagreements, bad relationships, etc. with someone, but is it entirely necessary to be 100% open about it?

Before Carrie Fisher died she wrote in her last book that she and Harrison Ford were sleeping together around the time of The Empire Strikes Back. And last night I came across a story about Britney Spears' sister Jamie Lynn Spears causing drama in her own book about some girl she used to act with on an old Nickelodion show and the poor relationship with her and Britney. Honestly, what is the fucking point, man? We all go through stuff in life and with people but to me it's not necessary to say everything you think or talk about everything you've gone through. Do they like airing all their dirty laundry?
