"The X Factor" season 3 finale will be the last show for Demi Lovato and she made sure it was one to remember as the "Heart Attack" singer dropped the F-bomb on the family show.

According to Hollywood Life, the show aired a segment accusing the singer of drinking "Annoying Juice" and cameras caught the 21-year-old looking upset.

In the clip the celebrity gossip site alleges that the series takes an insensitive jab at the singer's struggle with her addiction to alcohol.

The segment was a joke to highlight the fact that Demi Lovato has been getting on Simon Cowell's nerve all season, and attributed it to the "juice" she's been drinking.

"The X Factor" then aired the digitally altered segment of previous footage to make it look like the "Neon Lights" artist was feverishly drinking a neon green concoction that contributed to her acting annoying.

It was clear that Lovato was offended by the clip that reminded her of her difficult past as the camera cut to her for a reaction shot and she angrily turned to fellow judge Kelly Rowland and said, "That's f***** up."

When host Mario Lopez asked the "Skyscraper" singer what she thought about the segment, through gritted teeth she answered, "I think it's very, very clear I don't drink anymore. 'Annoying Juice' has become my new favorite drink and I love it because I get to annoy Simon with it."

Despite dropping the F-bomb in which she was probably unaware that she was on camera at the time, the singer handled the situation maturely and quickly moved on from the awkward subject.
