When former star of The OC Autumn Reeser decided to tie the knot with her longtime sweetheart, writer-director Jesse Warren, she had but one request:

She wanted to get married under a tree.

On May 9, her dream came true when she exchanged self-penned vows with Warren, 31, under a 200-year old oak at the Ojai Valley Inn & Spa in Ojai, Calif.

Wearing a gown by designer Carolina Herrera, Reeser, 28, walked down the aisle, which was decorated with white rose petals, in front of 200 friends and family.

"It was an incredible day, filled with so much love and joy," says Reeser, who played Taylor Townsend on the FOX hit show. "It surpassed all my expectations."

Hopefully Jesse Warren was able to handle what happened later that night. We hear Autumn is a terror in the sack. Oh, wait, that was Taylor Townsend. Sorry.

After dinner, it was time to hit the dance floor. Says the glowing bride: "I loved dancing with my husband and our friends and family at the reception."

Next up for the cutie? Reeser will appear in HBO's Entourage.
