Robert Pattinson and Katy Perry Crash Wedding Rehearsal

Guest Stephanie Sands, who was invited to the practice, told People that the bride spotted the A-listers “Just sitting next to each other watching the wedding rehearsal in the main courtyard area” of San Ysidro Ranch in Montecito.

"They were dressed very casually,” Sands explained. “She was wearing a hoodie and big sunglasses. There was no PDA between them and no body language that showed they were dating. They just sat together and watched."

Stephanie added that she had “no idea” why the longtime friends were at ranch, explaining they were “not affiliated with the wedding party and were not seen mingling with guests.”
