Robert Pattinson & Katy Perry's Wedding Rehearsal Crash Thrilled Guests: Relative

How would you feel if Robert Pattinson and Katy Perry showed up at your wedding rehearsal?

"It was extra exciting for Tanya and John," said a close family member of bride Tanya Mayer, 23, and groom John Rocotta, 26, whose rehearsal at the San Ysidro Ranch in Montecito, Calif., was crashed Saturday by the stars.

"They were just sitting quietly and talking," the relative told PEOPLE, "and we were on the lawn nearby. We respected their privacy."

Pattinson and Perry appeared in the main courtyard of the ranch and watched a procession of parents and grandparents before the bride walked down the aisle.

The unexpected guests were the talk of the wedding the next day, Sunday, which was, according to another relative, "all-inclusive," to represent the diverse backgrounds of the wedding couple's parents.

"It was a Jewish-Catholic-Hindu ceremony," the second relative told PEOPLE.

The newlyweds are now off on their honeymoon in Thailand.
