On September 22, “The Queen of Country Music,”  Reba McEntire, celebrated the 40th anniversary of her Grand Ole Opry debut.

Back in 1977, another country queen, Dolly Parton, surprised her and  40 years after, she did it again. History does repeat itself! She unexpectedly wound up onstage, but in a very different way than she did when she unintentionally ended up cutting McEntire’s big debut short.

“She had just come in the parking lot and they said, ‘Reba, we’re going to have to take one of your songs (for Dolly),’” McEntire recalls about her debut. “I said, ‘It’s okay with me. Can I meet her?’ I was thrilled to death.”

Instead of cutting her set short, this time instead of taking one of her songs, she helped present McEntire with an intricate, three-tier cake.

“I can’t believe Dolly Parton was here to surprise me,” McEntire captioned a photo of the country queens on Instagram.

Vince Gill also showed up to honor his fellow Oklahoma native and longtime friend. Gill is a mainstay of the Opry, and he was also on hand to help honor his fellow Oklahoman and friend.Another special surprise is commended country artists Vince Gill and Carrie Underwood.  Of course, McEntire closed her notable performance with a bang. It’s none other than her fierce and blazing version of “Fancy.”

Carrie Underwood also joined McEntire for a duet on her song “Does He Love You.” She also showed how much of a fangirl she really is when she posted two pictures from the evening to Instagram.

“How is this my life?” Underwood said on social media, sharing a picture of herself with Parton, McEntire, and Gill. “I got to be part of this crew celebrating @reba ‘s 40th anniversary of her first @opryappearance! Three legends…and me!!! So many dreams came true tonight!#OnlyAtTheOpry”

She shared another photo of herself with Parton, McEntire and Gill backstage, writing, “Pretty sure we’re all besties now.”

After leaving the stage, Underwood reacted with amazed disbelief.

“Last night was a DREAM. Happy 40th #Opry debut anniversary, @reba!” the Grand Ole Opry official Twitter page posted.

McEntire was officially inducted as a member of the Grand Ole Opry on January 17, 1986. I think it’s amazing how much Reba has gone through to survive in this tough music industry for four decades! Atta girl!
