Royal wedding number two!

Just three months after Prince William and Kate said "I do" at Westminster Abbey, the Duke of Cambridge's cousin, Zara Phillips, is getting ready for her own royal wedding. On Friday, Phillips, 30, was seen with her soon-to-be hubby Mike Tindall leaving their wedding rehearsal and Canongate Kirk in Edinburgh, Scotland.

An insider told Us Weekly the duo arrived in a Jaguar. The accomplished equestrian looked laid-back and happy as she left the church. She wore a cardigan, jeans, flip-flops and sunglasses with her hair pulled back. Her fiance also wore jeans. "Zara hugged Mike's arm before they went their separate ways after the rehearsal," a source added.

On Friday night, the wedding party will celebrate aboard the Royal Yacht Britannia.

Phillips and Tindall, a 32-year-old Rugby player, announced their engagement in Dec. 2010. Their official wedding will be held on Saturday at the church, which is decked out with white roses and beech tree branches. Their private reception will be held at the Palace of Holyroodhouse, one of Queen Elizabeth's official residences.

An insider told Us that William, 29, Kate, also 29, and Princesses Beatrice and Eugenie all arrived to Edinburgh around the time of the rehearsal on Friday. Zara's mother Princess Anne was  in attendance Friday at the wedding rehearsal.
