The event was attended by about 120 guests at sunset in a canyon setting in the northern part of Malibu.

Shannen Doherty and Kurt Iswarienko, who dated for two years, said their “i do’s” in front of friends and family in a lavish outdoor ceremony in the beachside community of Malibu.

The ceremony was simple and elegant, with the walk way to the pagoda running over a swimming pool.

Shannen Doherty wed Kurt Iswarienko under the pagoda which was covered with white silks and surrounded by white rose petals.

The entire congregation had been asked to wear black, with even the bridesmaids decked out in the classic color.

Shannen Doherty looked stunning in an off-white strapless gown with a black sash. The actress wore her hair down and in loose waves.

The wedding ceremony itself lasted for about 30 minutes before guests were ushered into a marquee tent nearby for the reception.

Shannen Doherty had been married twice before, to actor Ashley Hamilton for a year and then to Paris Hilton’s sex-tape co-star Rick Salomon from 2002 to 2003. Both marriages lasted less than a year.

In 2010, Shannen Doherty told People Magazine: “Marriage to me is such a gigantic commitment that it’s not something I’d ever go into lightly anymore.

“I’ve learned my lesson.”
