Jessica Simpsonis revealing new details about her relationship with alcohol in 2017.

While sitting down for an interview withHoda KotbonToday,the singer admitted to having a “weak moment” and drinking before a May 2017 appearance onThe Ellen DeGeneres Show.

“I can’t even watch the interview,” the 39-year-old, who recently opened about herstruggles with addiction, explained. “It was a weak moment for me, and I wasn’t in the right place.”

At the time, Simpson admitted she “knew that I wasn’t present,” adding “I knew that something was off.”

Kotb explained in the exclusive clip that several fans “wondered if she’d been drinking” after seeing her interview with DeGeneres — to which Kotb revealed, “she had.”

“I had started a spiral and I couldn’t catch up with myself and that was with alcohol,” Simpson told Kotb.

Viewers of Simpson’s appearance onEllencalled the interview “painful to watch” and noted that she could “barely put together a coherent sentence.”

Simpson writes about her battle with addiction in her upcoming memoir,Open Book(out Feb. 4, along with heraudiobook)which was exclusively excerpted in PEOPLE.

The star reveals for the first time that she was sexually abused as a young girl. The resulting emotional pain, along with other stressors, including career pressures, led her to self-medicate with alcohol and stimulants — a dependency that would later prompt her doctor to tell her her life was in danger.

“I was killing myself with all the drinking and pills,” she writes.

The star got sober in November 2017 and hasn’t had a drink since. “Giving up the alcohol was easy,” she says. “I was mad at that bottle. At how it allowed me to stay complacent and numb.”

In one of the book’s most moving scenes, she writes about hitting rock bottom after a Halloween party at their home in late 2017. That’s when she told her closest friends: “I need to stop. Something’s got to stop. And if it’s the alcohol that’s doing this, and making things worse, then I quit.”

“Eric gave up drinking the second I did,” she says. “He said, ‘I’ll do it with you, babe.’ It was like no biggie and he hasn’t gone back or looked back.”

“It’s just the way he is,” she says. “He’s a very selfless and loving person who is the most incredible father on the planet.”
