The couple are celebrating
The actress is said to be ‘extremely happy and very excited’ to be expanding her family.
Penelope, 38, and Javier, 43, started dating in 2007 after being friends for years and married in the Bahamas in July 2010.
They welcomed son Leo Encinas in January 2011.
Vanilla Sky star Penelope has previously spoken about how fulfilling she finds being a mother.
‘From the first second, you feel so much love. It is a revolutionary experience. That’s the best way I can describe it,’ said Penelope.
‘Nature is very wise and gives you nine months to prepare, but in that moment, when you see that face, you are transformed forever.’
