Louis Tomlinson posted a photo via Instagram last Thursday, February 16, 2017 which stirred a wave of hate comments just because of Bella Thorne.

According to Hollywood Life, Louis Tomlinson is showing himself posing alongside a girl band he is reportedly managing with "X Factor" Simon Cowell. The 25-year-old former "One Direction" band member captioned it simply with "Exciting."

Bella Thorne had casually responded "awww", a pretty sweet and inoffensive comment that stirred hate comments and death threats from the "One Direction" fandom, Seventeen reports.

Louis' fiercely loyal followers came for Bella, throwing insults and threats like, "stay in your own damn lane honey," "go execute yourself," "please don't take him he's pure," and "don't go near him bc 1D fandom will kill."

Others cruelly slut-shamed the star, with some saying "stop trying to date every man on this planet", and other comments "you're in the wrong place. Backoff."

While some social media users attempted to defend Bella and diffuse the unpleasant situation, most were "warning" her keep away from the pop star, which escalated into unnecessary death threats. To make matters worst, the harsh comments continued on the 19-year old former Disney actress' latest Instagram photo as well.

Bella appears to have responded to the backlash by online trolls, writing on Twitter: "Hahahahaha got your panties all in a bunch me being a little pot stir as usual #littledevil let me live my life yo!!! Go live yours."

Bella Thorne's romantic relationships have been highly-publicised of late, linked to "Marvin Gaye" singer Charlie Puth and "Teen Wolf" actor Taylor Posey. Thorne is allegedly dating former British "Big Brother" contestant and controversial YouTuber Sam Pepper.
