Gruffudd and Evans met on the set of 102 Dalmations
Welsh actor Ioan Gruffudd, star of Hollywood blockbusters such as the Fantastic Four and ITV's Hornblower, has become a father for the first time.
The 35-year-old Cardiff actor's daughter, Ella Betsi Evans Gruffudd, was born in Los Angeles on Sunday.
He and his wife Alice Evans, who is also an actress, live in LA. They first met filming 102 Dalmations in 1999 and married in Mexico in 2007.
American magazine People reported that Ella weighed 6lbs 3oz.
The couple announced the pregnancy in April.
Before the birth, Gruffudd said of himself and his Lost actress wife Evans: "I'm sure we have no idea what we are heading into.
"But we both love each other so much and really hope that we will create an environment of love and happiness."
Gruffudd has also starred in the film King Arthur, and played an officer in Titanic, the highest-grossing film ever made.
