Oprah Winfrey has unwittingly been labelled the "other woman" as her growing dependence on TV psychologist Dr Phil McGraw puts further strain on his already fragile marriage. Still reeling from the abuse scandal in her South African school — an event she describes as "one of the most devastating experiences of my life" — Oprah has turned to Dr Phil for emotional support. They have been burning up the phone line for hours-at-a-time counselling sessions. "I think she was absolutely devastated by what took place there. It absolutely destroyed her," Dr Phil has confirmed. But friends say Oprah's constant neediness has caused Dr Phil's exasperated wife, Robin, to liken her to the "other woman" in their marriage. "It seems like when Phil isn't working, he's on the phone to her," she told friends.
