Jason Momoa wanted to keep his wedding with Lisa Bonet private and out of the public eye.

On Thursday, the "Aquaman" star's secret wedding with Bonet made headlines. And during a press junket for Momoa's upcoming film, "Justice League" over the weekend, he revealed that he is not happy that their nuptials made it to news outlets and tabloids. He also vowed to find the person who spilled the beans about his wedding to Bonet.

"I thought it would have stayed that way, but some [person] leaked it and I will find you," Momoa told Entertainment Tonight. "You know what, I've been married to my wife for 12 years. It's just a gathering of our families and celebrating our love."

Momoa's co-star, Ezra Miller, quickly denied that he was the one who revealed the news of his secret wedding. "I swear it wasn't me," Miller said.

The "Game of Thrones" star and Bonet have been rumored to be married since November 2007. However, it was not until last month that they decided to make things official. "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.'"

For their wedding, Momoa wore an unbuttoned white shirt and lei. He styled his hair into a man-bun. Meanwhile, there were no photos or reports as to what Bonet wore on her big day, but the bride reportedly "looked beautiful."

Among Momoa and Bonet's wedding guests were Chris Sharma, Alicia Vikander, Michael Fassbender and several other actors that the "Conan the Barbarian" star worked with in the past. Their children -- Lola, 10, Nakoa-Wolf, 8 -- along with Zoë Kravitz, Bonet's daughter with ex-husband Lenny Kravitz, were also in attendance.

Momoa and Bonet met through their mutual friends in 2005. However, the "Frontier" actor admitted that he has had a crush on her since her stint on "The Cosby Show."

"When I first met her, she didn't know I was a stalker, but I was. I was with one of my best friends and when I turned around, and they were going to introduce us, literally like, FIREWORKS," Momoa said about their first meeting. "She said 'Hi I'm Lisa'. And I said 'Hi, I'm Jason' and I just turn around to my buddy like... [freaking out]. Inside, I was like a little girl and I [deepened my voice] and tried to pull it together. She definitely makes me shy. It's been an honor."

Momoa added that he didn't tell Bonet that he stalked her until they had two children together. Since the first time he saw her, he was certain that she's the one for him. "That was the first time when I was like, 'I want that one. I want her. I'm going to get her,'" Momoa confessed. "'I kinda stalked ya. I was going to find ya.'"
