Aquaman is off the market! Jason Momoa and longtime girlfriend Lisa Bonet secretly tied the knot last month, according to Us Weekly and People.

An insider tells Us Weekly that the two exchanged vows in October in Topanga, California, saying, "Apparently they weren't officially married until then! They said they 'made it official.'"

According to People, reports that the two were married in 2007 are not true. The "Cosby Show" regular first met through mutual friends in 2005 and went on to have kids Lola, 10, and Nakoa-Wolf, 8.

A source told Us Weekly that the couple purchased a marriage license on October 2, a week before the wedding.

Among the guests were Lisa's daughter Zoe Kravitz and her "X-Men: First Class" costar (and former boyfriend) Michael Fassbender, who attended with new wife Alicia Vikander.
