Actress, and former "Cosby" star, Lisa Bonet and her husband Jason Momoa welcomed their second child in late December, reports US Magazine.
The couple named their baby boy Nakoa-Wolf Manakauapo Namakaeha Momoa.
"He was born on the stormest, rainy night," Jason's mother wrote on the proud papa's official site's message board, adding that the weather influenced the lengthy name.
"Nakoa (warrior)... Mana (strength/spirit) Kaua (rain) po (dark)...," she wrote. "The [first] name was always going to be Nakoa-Wolf."
The new addition to their family is the couple's second. Their first, Lola Iolani, was born in July 2007. Bonet also has a 20-year-old daughter named Zoe with ex-husband Lenny Kravitz.
Bonet currently stars on ABC's detective drama "Life On Mars," while Momoa acts on the Sci-Fi Channel's Stargate: Atlantis.
