Queen Elizabeth is a great-grandmother once again!

Her grandson Peter Phillips and wife Autumn have welcomed a baby girl, Isla Elizabeth Phillips.

“The Queen, the Duke of Edinburgh, the Princess Royal, Captain Mark Phillips and Autumn’s family have been informed and are delighted with the news,” a Rep to the Royal Family announced.

Baby Isla was born last Thursday and will be 13th in line to the throne (Peter’s mother is Princess Anne).

This is the second baby and girl for the couple who have a 14-month-old daughter, Savannah.

Congratulations!!!
