Jenna Fischer's July 3 Malibu wedding to writer Lee Kirk was one to remember, says her Office costar Rainn Wilson.

"Went to the most beautiful wedding I've ever experienced," he writes on Twitter. "Total Love, Jenna Fischer & Lee Kirk!" first reported that Fischer, 36, and Kirk -- who have been dating since January 2008 -- wed Saturday.

They got engaged last summer while vacationing in Europe.
