Selena Gomez gave some advice for newcomers who’ve experienced their first taste of success in Hollywood. During a new interview for Vanity Fair‘s 29th Annual Hollywood Issue, 30-year-old Gomez said, “All I can say is, I would love to be there for you if you ever have questions.”

Gomez continued, “But this industry is a beast. It’s really scary to see what happens when you’re given so much power and money at a young age. I think it’s extremely scary. The bigger you get, the more humble I would encourage you to be. Hold on to your heart, try to be the best you can be and be careful about who to trust because you are who you surround yourself with.”

The actress and singer shared that her little sister, Gracie Elliot Teefey, said she doesn’t want to be in the entertainment industry. Gomez said, “My sister’s 9, and thank God she doesn’t want to be in this industry. Actually, that’s her now. What if she tells me in two years she wants to? I can’t even think about it.”

Gomez started her career as a child actor on “Barney and Friends,” then shot to fame while starring on the Disney Channel show “Wizards of Waverly Place.” Recently, Gomez starred alongside Martin Short and Steve Martin in “Only Murders in the Building.” Gomez says there were things she couldn’t say as a Disney star. She said, “I wasn’t a wild child by any means. But I was on Disney, so I had to make sure not to say ‘What the [expletive]’ in front of anyone. It’s stuff that I was also putting on myself to be the best role model I could be. Now, I think being the best role model is being honest, even with the ugly and complicated parts of yourself.”

Gomez has been open about her struggles with mental health throughout her career. In 2014, the former Disney star entered a mental health facility shortly after she was diagnosed with lupus and later revealed she had been diagnosed with bipolar disorder.

In a 2020 interview with Elle magazine, the actress explained, “My lupus, my kidney transplant, chemotherapy, having a mental illness, going through very public heartbreaks — these were all things that honestly should have taken me down. Every time I went through something, I was like, ‘What else? What else am I going to have to deal with?'”

Gomez has included her mental health work in her business ventures. In 2020, she launched Rare Beauty to “create a safe, welcoming space in beauty – and beyond,” according to the brand’s mission statement. The brand includes the Rare Impact Fund, which raises money for mental health services. Gomez hasn’t just had a successful acting career. She also released music with her band Selena Gomez & The Scene before launching her solo career. She’s known for hit songs such as “Lose You to Love Me,” “It Ain’t Me,” and “Love You Like a Love Song.”

Gomez has had a successful career in numerous arenas, but she still believes that being a star in Hollywood isn’t a walk in the park.
