Casey Affleck has become a father for the second time. The 32-year-old actor - who is the younger brother of Hollywood heartthrob Ben Affleck - and wife Summer Phoenix recently celebrated the arrival of their son.

Both mother and baby are said to be doing well.

The couple - who already have a three-year-old boy Indiana August - are yet to release any further details about the birth.

'Gone, Baby, Gone' star Casey and Summer - the younger sister of actors Joaquin and the late River Phoenix - married in June 2006. They got engaged in New York over the 2003 Christmas holidays and had their son the following May.

Before their nuptials, Summer - who is best known for her role in the 1998 teen horror flick 'The Faculty' - revealed why she loves Casey. She said: "He is a bleeding heart. He is the most generous guy I have ever met."
