Vinnie Levine / MEGA Sarah Ferguson could follow in Prince Harry's footsteps and release an explosive tell-all memoir after being stripped of her duchess title and losing her home. "Money has never been an issue for Sarah," a source told Daily Express. "She spent more than she had, and somebody else always picked up the tab. She's been very well taken care of over the years by various boyfriends, friends and acquaintances." "Yet for the first time in a good while, she is now seriously worried about how on earth she's going to maintain her lifestyle," the insider continued.
