Ben Affleck and Jennifer Garner will chose a traditional name for their unborn child - because the actor dislikes "trendy" baby names in Hollywood.

The couple, who share two-year-old daughter Violet, are expecting their new addition later this year.

But Affleck has vowed not to follow in the footsteps of celebrity parents with an unorthodox name for their new baby, reports U.S. magazine Star.

A source tells the magazine: "Ben put his foot down and said no way to trendy Hollywood names. If it's a boy, he likes the name Benjamin, not just because it's his name but it's that of his hero, Benjamin Franklin."
