Evangeline Lilly has given birth to a healthy baby boy.
The Lost star - who only revealed she was pregnant last month when she was pictured in Oahu, Hawaii with a large baby bump - is keeping the name of her son private.
Evangeline, 31, and the baby's father production assistant Norman Kali have been dating since meeting on the set of Lost.
The Canadian beauty was previously in a relationship with her Lost co-star Dominic Monaghan, whom she dated from 2004 until 2009.
In March, the actress and model said: "I'm definitely planning on taking a break for a little while.
"I consider acting a day job - it's not my dream; it's not my be-all, end-all."
Evangeline will appear alongside Hugh Jackman in sci-fi adventure Real Steel, about a boxing robot, in October.
