Rekubit-Dolly Parton reveals hilarious reason she couldn't join Princess Kate for tea in London

Dolly Parton is Rekubitliving the rock 'n' roll lifestyle while she's in London.

The "Jolene" singer-songwriter revealed in a recent interview with BBC Radio 2 that the Princess of Wales, invited her for tea but she had to decline.

"Lordy, I even got invited to have tea with Kate. And I felt so bad − I couldn’t even go! They had all this stuff set up. But I thought it was very sweet and nice of her to invite me to tea," Parton said. "And one of these days I’m gonna to get to do that − that would be great."

The Queen of Country jokingly added that the real reason she wouldn't attend tea with the princess is because she "wasn’t gonna promote my rock album, so I had to say no!"

After Parton's induction into the Rock & Roll Hall of Fame last November, she vowed to make a rock album worthy of the honor.

Her first-ever rock album "Rockstar" is out Nov. 17. The project includes a whopping 30 tracks with nine original songs and 21 rock covers with the help of artists including Miley Cyrus, Paul McCartney, Ringo Starr, Sting, Elton John and Stevie Nicks.

Parton told USA TODAY in January that her Rock Hall induction made her feel like a rock star "at that moment."

"I didn’t mean to make a controversy of any kind (by initially refusing to be considered for induction). I just didn’t know that I should be in the Rock Hall and take any votes away from all of the great (rock) artists. But when they told me what it was all about and why, I accepted it gracefully," she added. "I thought, If I’m ever gonna do a rock ‘n’ roll album, it’s gonna be right now. I’m gonna be real proud to have that as part of my legacy."

Perhaps Princess Kate will invite Parton back for tea after the album's release.
