Pete and Ashlee Celebrate at Rehearsal Dinner | Ashlee Simpson, Pete Wentz
The night after celebrating their bachelor and bachelorette parties, Pete Wentz and Ashlee Simpson kicked off their wedding weekend with a traditional rehearsal dinner.

The intimate party was hosted by Wentz's father Pete and mother Dale, who traveled to Los Angeles from their home in Chicago earlier this week. It was held at the Beverly Hills home of Jessica Simpson, who will be Ashlee's maid of honor.

The Wentz and Simpson clans celebrated on Friday night with a small group of friends and family at the indoor-outdoor affair, which featured candles on white tables and twinkling lights in the trees.

A source close to Jessica, who hosted Ashlee’s lingerie-themed bachelorette party on Thursday night, tells PEOPLE that boyfriend Tony Romo will attend the wedding with Jessica this weekend.
