It was a nice day for a Woody wedding.

E! News has confirmed that Woody Harrelson tied the knot with Laura Louie, his girlfriend of 20 years, in Maui on Sunday.

True to laid-back, beach-loving form, a rep for the 47-year-old actor duo said the “proud parents” and longtime partners swapped vows on the island in an intimate ceremony attended by family and friends.

While there’s no official word on a guest list for the perpetual bro and his 43-year-old better half, Us Weekly reports that Harrelson’s fellow shirt-eschewing pal Owen Wilson, Willie Nelson and Sean Penn were among those present. The mag also claims that none other than Alanis Morissette took over wedding singer duties.

It’s the second trip down the aisle for Harrelson. The longtime couple already has three children together, daughters Denni Montana, 15, Zoe Giordano, 23, and Makani Ravello, 2.woody-harrison1
