AceShowbiz - Elle King is sharing her side of the story after facing backlash for her controversial performance at Dolly Parton's 78th birthday tribute show back in January. During her appearance on Chelsea Handler's iHeartRadio podcast "Dear Chelsea", Elle revealed what happened prior to the show as well as the aftermath.

"I had been going through something very heavy and traumatic in my life at the time," she shared in the Thursday, May 16 episode of the podcast. "That day was a really big day dealing with what I was going through and am still going through, and I suffer from severe PTSD."

The 34-year-old star said that ahead of the tribute, she "hadn't eaten" and "slept in days" due to stress. "I was really overwhelmed," she recalled. "I was like a shell of myself."

"There was a big snowstorm that day, and this other singer who's supposed to be the headliner backed out like three hours before, and they asked me if I would sing-if I would be the headliner and sing 'Jolene'. I was like, 'Great, I know that song,' " Elle continued.

Elle finished one of her performances that night without a hitch. However, she admitted that she "took one shot too many" before her second appearance, prompting her to forget the words to Dolly's 2001 hit "Marry Me". During her drunken performance, she even told the audience, "You ain't getting your money back."

Of the mess, Elle said in the new interview, "I'm just not there in my body, I'm not there. I don't even remember what I said." The singer added, "I got the curtain dropped on me, and I was totally disassociated, and I just cut to the dressing room-me on the floor just sobbing, like, 'What have I done?' "

Back in March, Elle expressed gratitude to fans who are still supporting her despite the controversy. "To everyone sending me love," Elle penned on March 10, "because I'm human and already talked to Dolly. I love you. To everyone who told me to k*ll myself, I love you too."

Dolly also showed love to Elle. "Elle King is a doll," the "9 to 5" hitmaker told E! News. "I called her, and I said, 'You know, there are many F-words. Why don't we use the right one? Forgiveness, friends, forget it.' "
