It seems Billy Ray Cyrus isn't quite ready for Miley Cyrus to keep getting older! The "Achy Breaky Heart" crooner took to Instagram to shout out to his daughter on her 23rd birthday Monday, sharing an adorable throwback picture to do the honors. While Billy Ray rocks a full-blown mullet in the cute close-up, Miley looks precious in a gingham dress adorned with bows, holding both her daddy and her teddy bear tight. Billy Ray captioned the photo, "Happy birthday @MileyCyrus! You've already had such an incredible year and I know that 2016 is gonna be even bigger!!!!! #HappyBirthdayMiley."
