Jessica Simpson and Eric Johnson are set to tie the knot at San Ysidro Ranch over the Fourth of July weekend, and X17 photographers snapped these photos of the wedding preparations today. From the flowers to the leafy walkway, the location looks stunning!

Party rental trucks arrived on Thursday to deliver chairs, golf carts, tables and plants, and while everything was being arranged, Simpson wasn't anywhere to be seen but her hubby-to-be hit the Sandpiper Golf Course in Santa Barbara with pals and future father-in-law Joe Simpson. Crews were setting up the tents and tables on Friday morning, so if the singer is thinking of walking down the aisle today, her planners better hurry it up!

Last night there was a rehearsal dinner, and a photographer on the scene tells X17online:
    "Jessica's family and friends gathered for dinner on the hotel grounds under a tent. Ashlee and Evan were there and Jessica's parents and all of Eric's family. It was low-key but absolutely beautiful."

The pair originally planned to wed on the Italian isle of Capri, but after realizing that it might be a bit of a hassle, they decided to have the ceremony in California.

Simpson and Johnson started dating in May of 2010 and they got engaged in November of the same year, and they have a daughter Maxwell and a son Ace.
