Singer Kate Pierson, one of the co-founders of The B-52s, married her longtime girlfriend Monica Coleman last weekend in Hawaii.

The brides, who began dating in 2003, shared the news on Facebook Tuesday.

“Married now!” Pierson captioned a photo of the couple.

“Coleman wore a silk gown in a dusty gold color and Pierson wore a pink silk and tulle dress,” PEOPLE.com reported. “Both women opted to accessorize with traditional Hawaiian leis.”

According to E! News, wedding guests included the other members of The B-52s. Singer Sia and her husband Erik Anders Lang served as witnesses. Fred Schneider, frontman for The B-52s, made the best man speech.

The 67-year-old Pierson released her first solo album, Guitars and Microphones, in February.
