"Hawaii 5-0" star Alex O'Loughlin and his girlfriend, surfer and model Malia Jones, welcomed a son on Oct. 25, the actor's rep confirms to Us Weekly. The couple announced their pregnancy in August, one day before O'Loughlin's 36th birthday.
The new parents have yet to reveal their son's name.
This is the first child for the duo, who both have children from previous relationships. O'Loughlin is father to son Saxon, 15, while Jones is mother to son Spike, 3. The pair made their red-carpet debut as a couple at the Ninth Annual G'Day USA Los Angeles Black Tie Gala in January.
O'Loughlin is in the midst of shooting the third season of CBS' "Hawaii 5-0" in Honolulu. The Australian actor's other notable TV and film credits include "The Back-up Plan," "August Rush," "The Shield," "Whiteout" and "Three Rivers."
Jones, 35, has appeared in magazines such as Sports Illustrated and Esquire. She has also been in commercials for Coca-Cola, VO5 shampoo and American Express.
