Hailey Bieber asks fans not to Troll Selena Gomez.

Hailey Baldwin Bieber - asked her combined 69.8M social media following to stop leaving mean/rude comments on his ex-girlfriend Selena Gomez's social media on her behalf.

The 26 year-old Rhode founder and the 30-year-old actress-singer are still following each other on Instagram and, while Hailey 'liked' Selena's most recent post on Sunday, her fans were not as nice in the comments.

Gomez's Instagram slideshow - titled 'Crazy about you Paris' - had a substantial amount of comments attacking her for 'playing the victim' and being 'jealous' of Bieber and 'copying' her style with one troll stating: 'Justin left you for a reason.'

'Just know that I don't want that, nor do I ever or will I ever support or condone hateful, mean, or nasty comments,' the Arizona-born IMG Model wrote via Instastory on Monday.

'Doing that is not supporting me. If you are participating in that you are a part of a culture that I want no part of. Please be nice or don't say anything.'
