NEW YORK —  ABC newswoman Elizabeth Vargas and her husband, singer Marc Cohn, are parents again, of another boy. Vargas and the baby, named Samuel Wyatt, are "doing incredible," said ABC representative Alyssa Apple, in an e-mail to The Associated Press on Wednesday.

Vargas and Cohn's other son is 3-year-old Zachary. Cohn has two children from a previous marriage.

In May, Vargas, 43, stepped down as the co-anchor of ABC's "World News Tonight" to take maternity leave. Charles Gibson became the sole anchor, replacing Vargas and Bob Woodruff, who was injured in Iraq earlier in the year.

Cohn, best known for his song "Walking in Memphis," won a Grammy for best new artist in 1992.
