Following the ceremony, the wedding party and guests were treated to an "Alice In Wonderland-themed" reception. The cake, by Sam Godfrey of Perfect Endings, was decorated with a variety "Wonderland" items including a top hat, teapot, stopwatch, with a pot of flowers crowing the top of the cake.

The centerpieces were reportedly made with black roses.

According to People, Ashlee is pregnant with the couple's first child. The couple has previously not confirmed news of Ashlee's pregnancy.
