Hailey Bieber opens up about being bullied by Miley Cyrus, social media anxiety

Hailey Bieber has revealed the emotional toll Instagram takes on her mental wellbeing and revealed that Miley Cyrus was her "biggest troll" as a child.

The TV star and model, whose surname was Baldwin before her marriage to Justin Bieber, is calling for more love and less hate on the internet.

In a series of posts on her Instagram story, Hailey slammed the social media platform and the people who make nasty comments on it.

"It's hard to focus on your wellbeing and mental health when each time you open Instagram someone is tearing apart your job, your relationship, or essentially any of the things in your life that are positive.

"I just don't believe we're called to live a life where we're so easily caught up in strangers' opinions on something they have NOTHING to do with. We need to take a step back and realise we need to express more love and encouragement to one another instead of consistently tearing people down and judging.

"And I won't let people make me feel like I'm doing something wrong by enjoying my life and being happy."

Although she heralds Instagram as "an incredible tool", she says it gives her "immediate anxiety".

"Being off of Instagram is the best thing ever. Whenever I take breaks from it I feel so much better... the second I come back on, I get immediate anxiety, I get sad and I get worked up. Don't get me wrong, Instagram is an incredible tool and a great way to stay in touch and interact with others. But the negativity screams so loud."

Meanwhile, Hailey stars in a new episode of Carpool Karaoke along with Miley and reality TV star Kendall Jenner.

The 'Wrecking Ball' singer admits picking on Hailey when they were younger, but says it ultimately helped her.

"Miley was the biggest troll to me. She prepared me for this industry," Hailey said. "My older sister and her used to gang up on me."

"I would be evil to her," Miley said. "She would try to play with us, like me and Alaia, and we would lock her out of the room.

"I had to. It made you who you are, you know? It made you stronger. Now you can always take, like, trolls and shit. Because I was such a troll."
