The 18-year-old model recently signed up to Twitter and has already received nasty comments from other users.

She told the new issue of Complex magazine: "This s**t is crazy! I was laughing about my life, like, oh my god, people are so psychotic. Some girl I don't even know commented on my picture a week ago, 'You should go kill yourself.' I just had to say something. I commented back, 'I just want to understand the sadness in your heart.'

"A lot of people say they know me and my life, but no one really does. Except for, like, my family and Bronte. It's frustrating. My whole thing is I'm trying to spread love to everyone. Some people don't see that, but I really am trying to spread positivity to people."

The blonde beauty - who is the daughter of Lionel Richie - took to Twitter in late November to announce her arrival.

She wrote: "Just a bit late to the twitter game (sic)."

And sharing a photo of her first tweet on Instagram, she captioned the picture: "Just a bit late but hi twitter (sic)."

And Sofia only knows too well about how to deal with online critics after her ex Justin Bieber shut down his Instagram account when fans sent him nasty messages about his then-girlfriend Sofia.

He said at the time: "I'm gonna make my Instagram private if you guys don't stop the hate this is getting out of hand, if you guys are really fans you wouldn't be so mean to people that I like. (sic)"

The comment started a public spat with Justin's ex-girlfriend Selena Gomez, who fired back: "If you can't handle the hate then stop posting pictures of your girlfriend lol - it should be special between you two only. Don't be mad at your fans. They love you (sic)."
