Baby-oil heiress Casey Johnson (below) denied to Page Six that she ransacked and robbed a friend’s apartment. Following Jasmine Lennard‘s claim that she’d broken into Lennard’s Hollywood place and stolen all of her clothes, shoes and jewelry — leaving a vibrator behind — Johnson was arrested for grand theft. But after getting out of jail on $20,000 bail this week, she told us: “Everything she has said is 100 percent fabrication. It’s not true. I’ve had a rough time. I’ve just got out of jail.” She added she was meeting last night with powerhouse lawyer Robert Shapiro and a crisis manager. Johnson added, “It is a very serious thing she is charging me with, so I am not going to mess it up by telling my side — as much as I’d love to. But the truth is far different that what Jasmine Lennard has said.”
