According to TMZ
, LED ZEPPELIN singer ROBERT PLANT obtained a temporary restraining order against 40-something-year-old Alysson Billings earlier this month, requiring her to stay 100 yards away from the singer at all times. But today a judge made the restraining order permanent, ordering Billings to stay even farther away - 300 yards - for the next three years. Plant claims Billings has been harassing him for the last three years - showing up at his concerts around the globe, sending him bizarre gifts and increasingly threatening messages. He says the woman believed they were in a relationship, even though they never met.
