Lisa Bonet announced she was pregnant in 1988. She and her then husband Lenny Kravitz welcomed their first daughter together, Zoë Isabella Kravitz. Shortly after, Cosby let her know that a pregnancy wasn't going to work for her character. "Lisa Bonet is pregnant, but Denise Huxtable is not," he told her (per TV Web). She wouldn't return to The Cosby Show until the following year, but it wasn't for long. She left the show for good in 1991. 

Bonet and Kravitz divorced in 1993. Two years later, she legally changed her name to Lilakoi Moon, as reported by E! News. She laid low for many years after, except for the occasional acting gig. In 2005, she began dating actor Jason Momoa. In 2007, the couple welcomed daughter Lola Iolani. The following year, they welcomed son Nakoa-Wolf Manakauapo Namakaeha, per PopSugar. The couple later tied the knot in 2017, though they were widely regarded as married before they "made it official," a source told Us Weekly.
