Tyler Hubbard and his wife revealed that the baby they are expecting is a boy in a theme party posted online on Thursday night (June 8).

The Florida Georgia Line singer and wife Hayley held a "Dirt Bikes or Diamonds" themed party to reveal the sex of their first child, attended by an intimate circle of family and friends that included Thomas Rhett's wife Lauren, who is pregnant, and Jason Aldean's wife Brittany, who is also expecting. Through a series of posts to Instagram Stories, they shared the action live, revealing their first child will be a son, first showing a cake with dirtbikes and blue frosting, then a small bit cut from the cake with a blue center and captioned "boy," and finally a picture of a tiny shoe marked "first pair of kicks."
