Demi Lovato Drops F-Bomb on ‘X Factor’ Season Finale: Did Producers Poke Fun at Past Alcohol Addiction in ‘Annoying Juice’ Segment? (VIDEO)

Demi Lovato was clearly upset during the season finale of the "X Factor" after producers aired a segment titled "Annoying Juice." It's no secret that the singer lovingly got on Simon Cowell's nerves throughout the season, and producers attributed it to the "juice" she had been drinking on the show.

In the clip Lovato was seen constantly sucking down some neon green drink as she took jabs at Cowell. The segment was meant as a joke but Lovato - who revealed that she struggled with alcohol addiction - didn't find it funny. While the clip aired she was visibly annoyed and at point looked at fellow judge Kelly Rowland and said "That's f**ked up."

When host Mario Lopez asked the "Hear Attack" singer what she thought of the clip she said "I think it's very, very clear I don't drink anymore [but] 'Annoying Juice' has become my new favorite drink and I love it because I get to annoy Simon with it."

Recently Lovato opened up about her past struggles with addiction during an interview with "Access Hollywood."

"Something I've never talked about before, but my drug use I could hide it where I would sneak drugs," she said. "I couldn't go 30 minutes to an hour without cocaine and I would bring it on airplanes."

"I would smuggle it basically and just wait until everyone in first class would go to sleep and I would do it right there," she continued. "I'd sneak to the bathroom and I'd do it."

She also said that she sometimes would start drinking as early as 9 a.m. and realized at 19-years-old she needed to make some major changes in her life.

"I had a moment where I was like, 'Oh my God... that is alcoholic behavior,'" she said. "[It's] no longer, 'I'm young and rebellious and having fun,' it was, 'Wow, I'm one of those people... I gotta get my shit together."
