Alan Jackson and his wife, Denise, will be celebrating their 30th wedding anniversary next month. The couple note they're grateful they've been able to weather three decades together. Alan adds that he's fortunate to have found such a committed partner in Denise.

Alan and Denise were high school sweethearts, and on December 15th, 1979 a 21-year-old Jackson married his 19-year-old girlfriend. They admit life together hasn't always been easy. Denise stood by Alan as he pursued a career in country music, which finally took off following their 10th anniversary. Nearly a decade later the demands of his career took a toll on their marriage. They separated at the end of 1997, but reconciled after a few months apart. Alan and Denise have three daughters together -- 19-year-old Mattie Denise, 16-year-old Alexandra Jane, or "Ali," and 12-year-old Dani Grace. The couple share more about their relationship and family as the cover story cover of the new "People Country," on newsstands now.
