Whale Rider's Keisha Castle-Hughes Has Baby Girl
The child, named Felicity-Amore, was born Wednesday at 6:35 p.m. and weighed 7 lb., 6 oz. Publicist Gail Cowan described the baby as "beautiful."
Castle-Hughes, 17, and Hull, 20, have been dating for three years and are based in New Zealand.
The Australia-born actress first made waves playing the fiery Paikea in 2002's Whale Rider – a role for which she became, at age 13, the youngest Best Actress Oscar nominee in Hollywood history.
"I thought I was still dreaming," she told PEOPLE at the time.
Since Whale Rider, Castle-Hughes played the Queen of Naboo in 2005's Star Wars: Episode III – Revenge of the Sith and was Mary in last year's The Nativity Story.
