After hosting the Teen Choice Awards in Los Angeles on Sunday night, Demi Lovato arrived in Florida this morning, where she'll tape two live back-to-back X Factor shows at the Fillmore Miami Beach on Thursday.

While this is for the most part a work trip, it looks like Demi's fellow judge Britney Spears wants to mix business with pleasure! Brit tweeted, "Congrats on your wins at the Teen Choice Awards @ddlovato! Let's celebrate when you get to Miami :)"

From the blonde hair to the heavy application of bronzer on her pretty face, it looks like the 19-year-old starlet will fit in perfectly in the MIA!

Demi Lovato is busy with her X Factor judging gig these days, but she's not too swamped to chat it up with Ryan Seacrest about her new job, her famous friends and hosting the upcoming Teen Choice Awards!

Demi loves her co-workers on The X Factor, but she wants to set the record straight about reports that she has a crush on creator/fellow judge Simon Cowell!:

“Oh my god. I don’t know where you heard that from. That’s ridiculous,” Demi says when asked about the rumors. “I mean, he’s a nice looking fellow and I know that the older ladies love him, he’s not my type. We have a lot of fun together and you know, deep down he’s a really cool guy.”

So what's it like working with Britney Spears?:

“She’s amazing and I’m having so much fun with her," Demi says. "You know, we obviously have both been through a lot so I think that we kind of just get each other a little bit. We’re still getting to know each other of course, but she’s just so much fun to work with, she’s really genuine and she’s kind of shy sometimes when the audience cheers for her. I think it’s really sweet that she’s so humble, but she’s also really, really funny on the show.”

When asked about her A-list pal Miley Cyrus and whether she's attending her upcoming nuptials, Demi replied:

“I don’t know when it is. I don’t even know if she’s planning it yet. I don’t know." Hmm, looks like someone's out of the loop!

Demi Lovato has been through a lot in her 19 years, and she recently opened up to Self readers about the life lessons she's learned along the way. Taking questions from fans, the X-Factor judge spoke candidly about her struggles with an eating disorder, cutting, and bipolar disorder.

On what she learned in rehab:

"I've spent the past two years getting over an eating disorder and issues like self-harming and bipolar disorder. Unlike a person who doesn't have these problems, I have to work on this stuff every day. I'm reminded of that whenever I eat or feel down."

On explaining the emotions behind self-harming:

"There were times I felt so anxious, almost like I was crawling out of my skin, that if I didn't do something physical to match the way I felt inside, I would explode. I cut myself to take my mind off that. I just didn't care what happened. I had no fear."

On being diagnosed with bipolar disorder:

"Finding out I had a real emotional disorder helped me put together the pieces of the puzzle. I remember being on my tour bus thinking, My life is so awesome right now, but I'm so depressed. Then, a few days later, I'd be on top of the world. It was really confusing. When I got diagnosed, my life made more sense."

On deciding to go public with her eating disorder:

"When I was younger, stick-figure thin was in and nobody was talking about eating disorders. I want girls to know that it's OK when they grow up and their body changes. I want them to be aware that certain things they might do to lose weight can be dangerous - life-threatening even."

Demi Lovato is showing the world why she was selected as a judge for X Factor.

The 19-year-old songstress, with heavily bleached blonde and pink locks, belted out her latest hit "Give Your Heart A Break" at Good Morning America's Summer Concert Series.

When asked about her hectic schedule, Demi told the GMA audience:

"I’m doing really good. I’m actually not tired, I get so much energy doing this stuff! I’m straight from tour to X Factor, to you know, everything!”

We're lovin' that Ms. Lovato is singing live. Perhaps her X Factor co-judge, Britney Spears, will take notice!

Demi Lovato is showing off her sexy curves in a stunning bright yellow Yigal Azrouel dress on the cover of Cosmopolitan. She definitely has the X Factor!

The 19-year-old "Skyscraper" singer, who was hospitalized late last year due a reported eating disorder, opens up about being diagnosed with bipolar disorder. Demi says:

"I felt relieved when I found out. Like I’m not completely crazy; there’s a medical reason for all of it. It’s a daily thing; you don’t get time off from it. And if I feel myself slipping back into old patterns, I have to ask others for help, which is hard for me to learn, because I really like doing everything on my own.”

So what's on tap for the X Factor judge? She adds, "I want to be married with kids in 10 years.”

Simon Cowell's doing something right!

The head honcho at The X Factor just signed on Demi Lovato as the fourth and final judge on the talent show, according to an E! News source.

Lovato will join Simon, L.A. Reid and Britney Spears at the judges' table when the show returns in September.

Fox won't comment on the news, neither will X Factor peeps, but reports claim Spears will get $15 million for a single season.

Cowell fired his frenemy Paula Abdul and Pussycat Doll Nicole Scherzinger in January, after the show's ratings were considerably below American Idol.

Demi Lovato has been very forthcoming with the public about her struggles with bulimia and cutting, and now the 19-year-old starlet is opening up about her battle with substance abuse.

Demi, who spent three months in rehab in November 2010, chats with the new issue of Fabulous Magazine and says she's thankful she ended her addiction before it became life-threatening.

“Being a celebrity can be dangerous,” she says. “Nobody says 'no'. That’s why so many end up overdosing and dying. It could definitely have happened to me." When asked about her drug use, Demi tells the mag, “It’s something I don’t really want to talk about. What I can say is that I was depressed. I would come off stage in front of 18,000 people and suddenly be alone in a hotel room. I’d come crashing down and would try to find a way to recreate that feeling, to stay 'up.'"

So how did she score the drugs? “Promoters gave me drugs and alcohol in restaurants or clubs,” she says. “They wanted me to come back so I would be seen there. They were basically kissing my ass ... I thought they were my friends. I thought I was having fun." But couldn't she have just said no?

Demi Lovato takes it all off... her makeup that is!

The "Skyscraper" singer ditched her usual heavy foundation, false lashes, and extensions for a more fresh-faced look, and we think she looks better without all the cosmetics. The Disney star has been vocal in the past about her insecurities, so we applaud her for having the confidence to let her natural beauty shine!

It seems the 19-year-old has gained strength since leaving rehab in January, and today she tweeted: "When there's smoke there's fire.. And I'm not gonna stick around just to be burned." Could she be referring to her ex, Wilmer Valderrama?

The That 70's Show actor has been making headlines in recent weeks for his hot new romance with Minka Kelly, so maybe Miss Lovato was let down after holding out hope for a possible reconciliation?

Stay strong, girl!
