Robin Gibb, who formed the Bee Gees with his brothers Maurice and Barry, has fathered a child with his live-in housekeeper, said the London Daily Mail this week. Gibb, now 59, is in an open marriage and had his wife’s approval for an affair with 33-year-old Claire Yang. But Dwina Gibb, a poet and former druid priestess, kicked Yang out of the house after she got pregnant. “At first Dwina was happy for Robin to sow his oats,” said a friend, “but she never expected him to actually plant his seed.”
