90210 diva Shannen Doherty's third wedding went off without a hitch this weekend -- the embattled actress exchanged vows with Kurt Iswarienko during a sunset ceremony in Malibu Saturday.

The wedding, which took placed at a private estate, was filmed for the season finale of Shannen's yet-untitled reality series on WEtv, which follows the actress through the the final months of wedding planning. The series reportedly began filming in August and was slated for a single season.

In 1993, when Shannen was still starring as Brenda Walsh on 90210, her fiancee Dean Factor (heir to the Max Factor cosmetics empire) called off their engagement and filed an order of protection against her after she allegedly threatened him with a gun and a promise that she would hire a group of men to sodomize him.

Not long afterwards, Shannen was married to Ashley Hamilton (George Hamilton's son) after a whirlwind two-week courtship - not surprisingly, the marriage only lasted a few months. In 2002, she married poker player Rick Salomon - of Paris Hilton sex tape fame - only to have it annulled a year later.

Doherty has been prone to professional breakups as well.  Despite being a major cast member, Shannen's continuous conflicts with castmates, drug and alcohol use, and Playboy spread led to her eventual firing from 90210 in 1994.

She returned to the small screen in 1998, when Aaron Spelling gave her another chance and cast her as one of the sister witches in the WB series Charmed. But conflicts with cast members again - Alyssa Milano, this time - led to her abrupt departure and replacement in 2001.

The same year, Doherty was arrested and charged with drunk driving.

Doherty, now 40, may have mellowed out after some years away from the glare of the spotlight.

Marriage to me is such a gigantic commitment that it's not something I'd ever go into lightly anymore, she told People magazine last year. I've learned my lesson.

According to his IMDB profile, Iswarienko is a film and television electrician, producer, and cinematographer.

Shannen and Kurt's reality series is set to premiere in January on WEtv.

People will see a side of Shannen they never expected to see, WEtv executive John Miller told People magazine in July.
