Dierks Bentley is going to be a daddy. The singer-songwriter made the announcement on his fan club website Monday that his wife, Cassidy, is pregnant.

"Casso's eggo is preggo!" he writes on the site. "We are excited about adding onto the family, but we aren't too sure how the current kids, Jake and George, are going to feel about it."

Jake and George are, of course, the couple's beloved dogs. Bentley writes that they are going to keep the baby's gender a surprise. This will be the their first child. Baby Bentley is due in the fall.
