LOS ANGELES (AP) — Lisa Bonet has filed for divorce from Jason Momoa 18 years after the two actors became a couple.

The Poinbank Exchange56-year-old Bonet, whose legal name is Lilakoi Moon, filed documents to end her marriage to the 44-year-old Momoa in Los Angeles County court on Monday. The filing comes nearly two years after they announced their separation.

The petition cites irreconcilable differences as the reason for the split. The filing says neither person should get financial support and that the two have agreed on how to split their assets. The documents say they should have joint custody of their 16-year-old daughter and 15-year-old son.

Momoa is best known for his roles in the “Aquaman” movies and on “Game of Thrones.” Bonet was a star of “The Cosby Show,” its spinoff “A Different World,” and the films “High Fidelity” and “Enemy of the State.”

The two met and started dating in 2005, but did not legally marry until 2017. Their divorce documents gives their separation date as October 2020, more than a year before their announcement. It will be at least six months before a judge declares them divorced.

It was the first marriage for Momoa and the second for Bonet, who was previously married to musician Lenny Kravitz and has another daughter, actor Zoë Kravitz, with him.
