The boy is the "Life on Mars" star's third child

Here's one celebrity baby name that's quite a mouthful.

Actress Lisa Bonet and her actor husband Jason Momoa welcomed a son, Nakoa-Wolf Manakauapo Namakaeha Momoa, during the first half of December, reports Usmagazine.com.

Momoa's mother says the boy was born on the "stormiest, rainy night," which led to his unique name. "Nakoa" means warrior. His first middle name is comprised of "Mana" meaning strength/spirit, "Kaua" meaning rain and "Po" meaning dark.

"The name was always going to be Nakoa-Wolf," writes Momoa's mother on his official website, "but Jason did the research on first [and] middle name."

"Namakaeha" is Momoa's Hawaiian given name, which translates to "all knowing eyes."

The couple's first child is Lola Iolani, 1. Bonet, 41, is also the mom to 20-year-old Zoe, her daughter with ex husband Lenny Kravitz.

Bonet is best known for playing Denise Huxtable, the artistic daughter on "The Cosby Show" and later on the spinoff "A Different World." On "Life on Mars," she plays Maya Daniels, the present-day love interest for Det. Sam Tyler (Jason O'Mara). Momoa acts on the Sci Fi Channel's "Stargate: Atlantis" as Ronon Dex.
