Country music icon Alan Jackson shared a rare family photo on Father's Day, featuring his wife Denise and their daughters, Mattie, Alexandra, and Dani Grace. The photo was likely taken at Mattie's recent wedding, which took place in May. Jackson and Mattie recently collaborated on a song and book titled "Racing The Dark" and "Lemons on Friday," respectively, with the latter featuring a foreword by Jackson and Denise. Jackson has remained mostly out of the spotlight since wrapping up his Last Call: One More For The Road Tour after revealing his Charcot-Marie-Tooth (CMT) disorder diagnosis in 2021.
