Royal-baby watch might go on a bit longer than expected—until January, that is. Zara Phillips, the daughter of the Princess Royal, announced on Monday that she is expecting her first child with her husband, rugby player Mike Tindall. It’s the third grandchild for the Princess Royal, Queen Elizabeth’s second child, whose son, Peter Phillips, has two daughters. “Everyone is delighted, really, really happy for everyone and both of them,” said Peter Phillips. The baby will be 16th in line for the throne. Phillips, an Olympic equestrian, plans on continuing riding while pregnant.
