Penelope Cruz and Javier Bardem have become parents to a baby boy.

The 36-year-old Spanish actress is believed to have given birth at Los Angeles' Cedars Sinai hospital on Saturday (22.01.11), but she and her husband are yet to name their son.

They were originally planning to have the baby in their home of Madrid - but changed their minds after spending Christmas in Los Angeles and deciding they wanted the child to have dual nationality.

The couple were joined during Penelope’s labour by her mother Encarna, her younger brother Eduardo and her sister Monica and her actor boyfriend Alex Gonzalez were present at the birth.

Javier's mother Pilar Bardem also flew out of Madrid's Barajas airport to the US on Monday (24.01.11) to meet her grandson for the first time, Spain’s HOLA! magazine reports.

Penelope and Javier started dating after working together on 'Vicky Cristina Barcelona' in 2007.

They were friends for over 12 years before they embarked on a relationship before marrying in a low-key ceremony in the Bahamas in July 2010.
