The "Really Don't Care" singer appeared alongside Sin City: A Dame to Kill For star Jessica Alba on Bravo's Watch What Happens Live Thursday. While there, Lovato, 21, agreed to play a round of "Plead the Fifth." Host Andy Cohen reminded the pop star that she could only skip one of the three questions.
"I'd kill Bieber. I'd kill Simon. F--k, I'd kill Joe, too!" Lovato said. "No, Joe and I are good friends, so I wouldn't kill him. I'd keep him around." Alba asked, "Who would you shag?" Lovato replied, "None."
The next question was hard to answer. "Not including your own behavior, what is the most scandalous thing you ever saw a Disney Channel star do?" Cohen asked. "And you don't have to name a name."
"I can't answer that!" Lovato said. "I plead the fifth."
Perhaps she should have saved that option. For Cohen's third and final question, he asked, "You recently unfollowed your BFF Selena Gomez on Twitter. So much speculation about this! Can you tell us why?"
"Um, I plead the sixth, if that's in the game," Lovato said. Cohen continued to probe the Camp Rock 2 star, asking, "Are people reading too much into it? Are they reading into something that doesn't exist?"
"I think it's just one of those things where people change and people grow apart," Lovato answered.
During the episode, Lovato was also asked to share her favorite memory of working with Britney Spears during the second season of The X Factor. "I didn't know what to expect when I was about to work with her. I just knew I was really excited," Lovato said of judging talent with the icon. "I just remember her having all these little moments where someone would come out on stage and she would just say it like it was. She didn't care! She would just say, like, 'I don't get it.' It was really funny and endearing the way that she would say it. I would just come off or across as a bitch. It was cute when she did it!"
Does Lovato really think she was seen as a bitch? "I'm a very honest person and I really just tell it like it is. You see it on my face," she said. "I always just wanted to focus on being constructive. Sometimes it was really hard because there wasn't anything constrictive to say. Like, 'Honey, it isn't going to happen."
