Gael Garcia Bernal is to become a father for the second time.

The 'Letters To Juliet' actor - who already has a 20-month-old son, Lazaro, with his girlfriend Dolores Fonzi - was delighted to share his "tremendous and complete happiness" over the pregnancy with his fans on twitter.

He tweeted: "Yes! We're making The announcement official: we've got a baby on the way. Tremendous and complete happiness that we share with all of you. Hugs and Celebration. (sic)"

Gael has been dating Dolores since December 2007.

The 31-year-old actor - who previously dated actress Natalie Portman - shot to fame after starring in 'Y Tu Mama Tambien' in 2001.

Earlier this year, he revealed he took on his role as Victor in 'Letters to Juliet' opposite Amanda Seyfried to "have fun".

He said: "I did the film just to have fun, to enjoy working with the group of actors that were here. To spend some time in Italy!"
