Singer-turned-actress Selena Gomez has spoken out about the "devastating" effects of social media on young people, saying it has been "terrible" for her generation, but said she tries to be a good example to her followers.

The 26-year-old star, who has 150 million followers on Instagram, made the comments at a press conference for her new film The Dead Don't Die, which was directed by Jim Jarmusch, at the Cannes Film Festival.

She said: "I think that our world is going through a lot obviously. What Jim [Jarmusch] gestured to in the film is that social media has really been terrible for my generation.

"I understand that it's amazing to use your platform but it does scare me when you see how exposed these young girls and young boys are.

"They are not aware of the news. I think it's dangerous for sure if people aren't getting the right information sometimes."

Selena Gomez says social media "has been really terrible for my generation"

When asked whether she has a responsibility to make platforms safer as she is one of the world's most prominent social media figures, Gomez said it was "impossible to make it safe at this point" as "there's no blocking anything, they're exposed to it immediately."

She continued: "I’m grateful I have a platform. I don’t do a lot of pointless pictures. For me, I like to be intentional with it."

The US star said that pervasive internet bullying "scares" her.

"I see these young girls… I’ll meet them at meet-and-greets, and they’re just devastated by bullying and not having a voice", she said.

"It can be great in moments but I would just be careful and allow yourself some time limits when you use it and when you shouldn't."
