Sir Michael Gambon is set to have a second child with his mistress at the age of 68.The actor - who plays Hogwarts' headmaster Albus Dumbledore in the 'Harry Potter' film franchise - already has 17-month-old son Michael with lover Philippa Hart and is said to be "worried" about how the news of the latest edition to his family will affect his wife Lady Anne, who he has been married to for 45 years.A family friend said: "Michael and Philippa are delighted that she's pregnant again, but he is very worried about what his wife thinks of all this. "He says it will cause him a lot of hassle if it comes out, but his private arrangements are so complicated he can't really expect a completely smooth run."Michael shares a London home with Philippa, but also spends time at his own apartment in the UK capital and at his family estate in Kent.When he is in Kent, he lives as man and wife with Lady Anne, who he has a 44-year-old son with.The friend added: "He continues to see his wife and mistress, but is very secretive about both relationships. He may be getting on, but Michael is sill a wizard with the ladies."
