"Deanna and I are overjoyed about this double blessing," said the Season 5 fourth-place finisher, 30. "Thank you for your expressions of love and support and for respecting for our privacy during this special time."

The singer -- who has gone on to front his own eponymous band, Daughtry -- detailed their struggle to get pregnant.

"Due to Deanna's partial hysterectomy in 2006, the couple used IVF and had their embryos transferred to a gestational surrogate," said a statement on the site.
