Reba McEntire is reflecting on her time with Dolly Parton.

The Reba star revealed that before Parton passed away on Aug. 25 at age 80, she received a call from the “9 to 5” hitmaker that went unanswered.

“She did call me at the end of July, and I was in a meeting and I missed her call,” McEntire told Entertainment Tonight of Parton in a recent interview. “I tried to get back in touch with her and I couldn’t. Never made connection.”

So, when a friend informed the 71-year-old that Dolly was “gone” a month later, “I thought, ‘I’ll never know why she called me.’”

However, the “Fancy” singer is hopeful that she’ll “find out one day.”

Although McEntire wasn’t able to speak with Parton in the weeks leading up to her death, she did remember their final conversation.

“Well, it took us a long time to connect because of our schedules and things,” McEntire explained. “And it was really special when we finally did connect and get to talk.”

While it was challenging to reach Parton, the “I’m a Survivor” singer expressed that she was particularly hesitant to end their last catch-up.
