In this week's cover story, PEOPLE goes inside the J.Lo nuptials of last Saturday, when the pop diva and choreographer Cris Judd, both 32, tied the knot. Among the details: Guests -- who had received hand-delivered invitations and directions the day before the wedding -- first gathered at Calabasas High School, a half-hour north of Los Angeles. At a checkpoint overseen by a team of six guards (the same security firm used by Brad Pitt and Jennifer Aniston at their wedding last year), they passed through a metal detector and were passed over a second time with a security wand. Cameras, cell phones and pagers had to be turned over in order for guests to board the buses that shuttled them the five winding miles up the mountain to the estate where the ceremony would take place. Upon arrival the guests mingled and enjoyed the panoramic views before being seated in white chairs arranged beside the willowy trees. Lopez entered around 6:15 p.m. Lopez's attorney Barry Hirsch presided over the nondenominational ceremony, in which the couple exchanged matching diamond-encrusted bands and traditional wedding vows. At 6:30 p.m. Hirsch pronounced the star "Mrs. Cristian Judd." Said a guest of the bride: "She wasn't nervous. She was radiating love."
