We love Dolly Parton for a lot of reasons, but perhaps at the top of the list is just how down-to-earth she is, despite being one of the most successful singers on the planet. Case in point: During a recent Sirius XM interview with radio host Andy Cohen, Dolly revealed that she and her husband, Carl Dean, love to hop in their RV and head to the Taco Bell drive-thru. Yes, folks, the secret to the couple's 50-year marriage might just be crunchy taco supremes. 

"Carl and I have a little camper, a little RV, and we're always driving through fast food restaurants to get our stuff," she explained to Andy. "That's one of the things we do. I'm always in the front seat. Sometimes they know me, sometimes they don't."

So what does the country music superstar like to order when she's making a run for the border? "I love their tacos. They also have little pizzas that I love," she said during the interview. But while she may love those Mexican Pizzas, she doesn't love it when her order gets messed up. "Sometimes I sign autographs on napkins [when we go through the drive-thru]. I don't mind any of that, but I really get mad if they mess up my order," she added. Fair enough!

But the low-key couple doesn't just hit up Taco Bell every time it's date night. "We do whatever feels happy and comfortable with us," she said on Sirius XM. "It's hard for me to get him to dress up to go to a nice dinner because he's just a country boy and hates that stuff. We do whatever's good. We have a good time."  Dolly and Dean, who tied the knot in 1966, are celebrating their 50th wedding anniversary on May 30 with a splashy vow renewal celebration.

Part of Dolly's interview with Andy also included a hilarious round of "Dolly Wood or Dolly Woodn't" — check it out below!
