LUKE BRYAN is in the January issue of "Good Housekeeping" giving up seven secrets that keep his marriage strong.  Here are some "highlights": 

"We don't have big throwdown fights.  If we have a beef, we always talk it out instead of letting it snowball." 

"We have coffee in the morning, just Caroline and me.  It's my favorite time of the day . . . anytime we can have 30 minutes to talk, it's just great."

 "We do little nights out together.  One Valentine's Day, we got each other's initials tattooed on our ring fingers!"

 "Every night before bed, I rub my wife's feet.  She says they're the best foot rubs on Earth."  (Check out the entire list here.)
