Creed frontman Scott Stapp and his wife, Jaclyn, are expecting their second child together next July, the singer's rep tells

"When Jaclyn told me we were having another baby, I was overwhelmed with joy and again reminded what this life is for," Stapp, 36, tells Us. "We are so thankful for God's blessings."

The two, who wed in February 2006, have a daughter, Milan, 3, and a son, Jagger, 11 (Stapp's child from a previous relationship, whom Jaclyn has legally adopted).

This past October, Stapp and his band released their first album in eight years, Full Circle. It debuted at No. 2 on the Billboard 200.
