LOS ANGELES : It’s finally official! Actor Woody Harrelson has wed long-time girlfriend, Laura Louie in Hawaii on Sunday, reports said.

With a group of family and close friends as witnesses, the couple who have been together for a good 20 years tied the knot in a simple and intimate ceremony, exchanging vows on the island.

Although a guest list has not been officially released, Us Weekly magazine reported that among those invited were actors Owen Wilson, Sean Penn and Willie Nelson while Alanis Morissette played wedding singer.

Prior to the ceremony, reports have said that there was a Hawaiian chant and blessing by a local minister.

The 47-year-old actor was clad in an aloha-print short sleeved shirt and cream coloured slacks, while Louie, 45, donned a white wedding dress.

Harrelson and Louie are already “proud parents” to three daughters, Makani Ravello, 2, Zoe Giordano, 12 and Deni Montana, 14.

Harrelson who met Louie back in 1987 when she was his personal assistant once raved to Los Angeles Magazine that Louie is “the ultimate goddess”.

“Sometimes I get way too yang. She's very yin. We balance each other very well,” he added.

Harrelson is perhaps most remembered for his role in “The People vs Larry Flynt” for which he garnered an Oscar nomination.

He was most recently seen in “No Country for Old Men,” “Semi-Pro” and “Seven Pounds”.
