The 25-year-old "Idol" season 11 winner got married on October 24 in Albany, Georgia in front of 250 of the couple's family and friends, reported Female First.
Phillips donned a Billy Reid tuxedo for the special day while Blackwell walked down the aisle in a Hayley Paige wedding gown.
The couple first met at an event for his sister's charity organisation Mission Change nearly seven years ago. They dated when he auditioned for "Idol" and got engaged Christmas last year.
