It's official, Jason Momoa and Lisa Bonet are married!

The "Aquaman" actor and the "Cosby Show" star have been rumored to be married since November 2007. However, the couple actually made things official just recently when they tied the knot in October. "Jason Momoa and Lisa Bonet had an official wedding a few weeks ago at their house in Topanga, California," an insider told Us Weekly. "Apparently they weren't officially married until then! They said they 'made it official.'"

Another source added that Momoa and Bonet purchased a marriage license from the Los Angeles County Registrar-Recorder/County Clerk's office on Oct. 2, a week before their big day.

As for their secret wedding, the "Game of Thrones" alum reportedly wore an unbuttoned white shirt and a lei. Momoa styled his hair into a man bun. Meanwhile, Bonet reportedly "looked beautiful," but there were no details about what she wore during the ceremony. Some guests reportedly performed a traditional Māori haka for the bride.

The couple's children -- Lola, 10, Nakoa-Wolf, 8 -- were present during the ceremony, along with Zoë Kravitz, Bonet's daughter with ex-husband Lenny Kravitz. Their guests also included Alicia Vikander, Michael Fassbender, Chris Sharma and several other actors whom Momoa worked with in the past.

"[Momoa] stays close with the people he works with on movies and is a really nice guy," the insider added. "It was a big party and people came from out of town to attend."

According to their relationship timeline, Momoa and Bonet met through a mutual friend in 2015. However, the "Frontier" actor has had a crush on Bonet since she played Denise Huxtable on "The Cosby Show." In fact, he had always wanted to work with her, which they later finally did when they played lovers in the film "Road to Paloma." "I always wanted to work with her," Momoa said of working with Bonet. "It's funny [though] — she made me shy."

Speaking of secret weddings, Vikander and Fassbender, who were among Momoa and Bonet's guests, also exchanged "I do's" secretly in Ibiza in October. The "X-Men: Apocalypse" star and the "Tomb Raider" actress were with their families and friends during their big day. They were spotted at the beach enjoying lunch before going on a cruise. The couple invited a professional photographer to document the event.
