Zara Tindall was a champion three-day eventing equestrian using her maiden name Zara Phillips. She switched to her married name this year.

Officials say the couple's second child is due in late spring.

Elizabeth, 90, and her 95-year-old husband Prince Philip already have five great-grandchildren.
