The first pictures of Earl Spencer's wife Karen and her baby bump have been revealed.
Princess Diana's brother Charles has been married to his Canadian wife since last June, when they tied the knot at the family's ancestral home, Althorp.
Princess Diana is buried the grounds of Althorp Park, in Northamptonshire, but would have been aunt to the new arrival.
The picture of heavily pregnant Karen was taken outside the majestic mansion, as the Olympic Torch made its way through the Midlands county.
This will be the seventh child born to millionaire aristocrat Earl Spencer.
Karen Spencer, nee Villeneuve, walked down the aisle as Earl Spencer's third bride. It is the former model-turned-social ambassador's second marriage, after a previous attachment to Hollywood Producer Mark Gordon, with whom she had two children, 11, and 13.
Prince William and Prince Harry's auntie, whose proper title is now Countess Spencer, attended Prince William's marriage to Kate Middleton.
The new addition to the family will be another cousin for the two princes, along with Princess Bea and Eugenie.
