On Sept. 13, Hachette Books revealed that Mayte Garcia, 42, whose four-year marriage to Prince ended in 2000, is writing The Most Beautiful, an “intimate memoir” about her relationship with the late singer and it's being released next April. Now, one of his friends tell In Touch this isn’t what he would have wanted.

“While Mayte isn’t going to slam Prince’s character, she isn’t going to hold back, either,” says an insider. “It’s a fine line, but she says she still loves Prince and wants to honor his legacy and be truthful.”
