Chris O'Donnell's New Child

``Batman and Robin'' actor Chris O'Donnell and his wife have added another baby to their nest.

O'Donnell's wife Caroline Fentress gave birth to their second child Christopher Eugene O'Donnell Jr. on Tuesday, the actor's publicist said Saturday.

The baby boy weighed seven pounds, nine ounces.

``They are all home and doing wonderfully,'' publicist Jennifer Allen said.

The couple, who have been married for about three years, also have a 1-year-old daughter, Lily Anne.

O'Donnell has starred in such films as ``The Bachelor,'' two ``Batman'' sequels and ``Scent of a Woman.''
