'Made In The USA' beauty Demi Lovato has revealed that she's so happy all of her fellow former-Disney pals are enjoying successful careers in the entertainment industry.

Speaking to MTV News, Lovato confessed that her contemporaries such as Miley Cyrus and Selena Gomez (pictured together with Taylor Swift, left) are doing so well and it makes her feel "proud" they all came from the same place:

"I'm so excited for Selena, I'm so excited for Miley... I get competitive as much as I love them. I do get competitive so I have to focus on myself and just be like it doesn't matter who has what, we are all equally successful, and in our lives it's a huge blessing. I'm so proud of everyone."

In the same interview, the superstar added that she often warns party girl Cyrus about going out and is very "protective" of her: "She knows how I feel about the whole partying thing. I love her to death and I'm always like, 'Just be careful' and she's like, 'Dude, I'm chilling. It's fine.' But I care for her so much that I'm so protective, but she's good. She's got a good head on her shoulders."
