Lili Reinhart did not realize a single tweet would place her under fire until she saw the backlash from the online community over allegations of racism. On Saturday, the "Riverdale" star uploaded a photo of a woman painted in black and claimed that she finally saw the perfect Halloween Costume that would reflect the color of her soul.

The internet reacts to Lili Reinhart's controversial Halloween costume idea

The 21-year-old actress said she saw the now-deleted photo on Instagram and did not expect it would spark outrage among her followers. Some deemed her a racist for using skin color to describe her soul, while others came to the defense of the CW star and thought there was nothing with her post.

After she saw the reaction from both her fans and critics, Lili Reinhart apologized and reassured the public that she did not intend to offend anyone with the photo she shared. The actress also acknowledged that her post was misinterpreted although she meant no harm when she uploaded the controversial photo she got from Instagram.

Celebrities accuse of doing blackface, racism

Lili Reinhart is not the first case an actress was accused of doing blackface for Halloween.

In 2013, Julianne Hough came under fire for a "racially insensitive" costume. During a Halloween party, the former "Dancing with the Stars" pro and judge appeared in prison jumpsuit and a tanned face.

It was further revealed that the actress was impersonating Uzo Aduba's character as Suzanne Warren in "Orange is the New Black." Julianne Hough was called a "moron" and "racist" by her co-actress Martha Plimpton despite her immediate response to the issue.

"It certainly was never my intention to be disrespectful or demeaning to anyone in any way," she explained. "I realize my costume hurt and offended people and I truly apologize."

Tyra Banks, on the other hand, had to apologize on behalf of "America's Next Top Model" contestants who were compelled to wear dark makeup for a photo shoot in 2011. "[If anyone was offended], I apologized because that was not my intent," she said amid the backlash.

Colton Haynes has also sparked online outrage for dressing up as Kanye West in 2012 and for impersonating Ghandi in 2013. The "Teen Wolf" alum immediately apologized for the several times that he has offended the public for wearing blackface.

Amid backlash surrounding Lili Reinhart's Halloween costume idea, an alleged old photo of Hillary Clinton wearing blackface has also emerged on the internet.
