Dolly Parton had a hilarious excuse to turn down tea with Kate Middleton

Not even the Princess of Wales could get an audience with the Queen of Country.

Dolly Parton, 77, told BBC Radio 2 that she received the invite from Kate Middleton, 41, while she was in London for work, but revealed that she was unable to make it.

“This time, Lordy, I even got invited to have tea with Kate but I couldn’t even go,” she shared. “I thought it was very sweet and nice of her to invite me and one of these days I’m going to get to do that — that would be great.”

The “9 to 5” singer went on to share the hilarious reason she turned the royal down.

“But she wasn’t going to promote my rock album, so I had to say no,” she quipped.

Parton also admitted that she wished she had more time to explore the city, but she ultimately doesn’t have time to do so.

“I love the people, the feel of London. I don’t unfortunately [get time to sightsee]. I have in the past, me and my band, in a tour bus when we have it planned,” she explained.

The Queen of Country is set to release her first-ever rock album titled “Rockstar” on Nov. 17. The album has 30 tracks, including nine original songs by Parton and 21 covers of iconic rock songs with features from artists such as Miley Cyrus, Paul McCartney, Ringo Starr, Sting, Elton John, Stevie Nicks and more.

“I’m so excited to finally present my first Rock and Roll album, ‘Rockstar,’” Parton said in a statement. “I am very honored and privileged to have worked with some of the greatest iconic singers and musicians of all time, and to be able to sing all the iconic songs throughout the album was a joy beyond measure. I hope everybody enjoys the album as much as I’ve enjoyed putting it together.”

The “Jolene” singer set out to record the rock album after being inducted into the Rock & Roll Hall of Fame.

She initially declined the nomination due to her background in country music rather than rock — but the RRHOF refused to take her off the ballot, with the foundation saying in a statement, “We are in awe of Dolly’s brilliant talent and pioneering spirit and are proud to have nominated her for induction into the Rock & Roll Hall of Fame.”

After learning that the RRHOF welcomes artists from a variety of categories, Parton backtracked her stance and said she would accept the honor, adding that it had “inspired me to put out a hopefully great rock and roll album in the future, which I have always wanted to do.”
