Socialite, Johnson & Johnson heir, and single mom of an adopted Kazakh baby Casey Johnson is moving back to New York from L.A.! Which reminded us of the myriad problems for her there: she turned down the opportunity to play the Nicole Richie role on Paris Hilton's The Simple Life. Her Beverly Hills mansion burned down last year. And she had that big fight with her thirty-years-older-than-her aunt, Libet Johnson, who she said stole her boyfriend while she was off scouring the globe for said baby. After the jump, re-hashing the gory details in an old Vanity Fair about what to do when Page Six calls after your rich aunt steals your man:

"Her first impulse was to hold her tongue. "I said I didn't have a comment, and then I looked at my assistant and I said, 'Goddammit, I have a comment,' " she says with a huge, dimpled smile, "and I went on my merry way and gave one." Went on her merry way—"just unloaded," as Richard Johnson recalls—and publicly accused Libet of seducing her boyfriend. "I think [my aunt] needs help," Casey told the Post. "I feel sorry for her. She's single. She's been divorced umpteen times. She's afraid to go out in public." And then Casey delivered the coup de grâce: "She was sleeping with my boyfriend, who I was in love with," she said. "An old woman with a lot of money is a very powerful aphrodisiac."
