Popular how-to website WikiHow has apologised after a cartoon showing Beyoncé, Jay Z and Barack Obama as white people appeared on its website.
WikiHow tweeted they were "disgusted and ashamed" after the 'whitewashed' image of the trio appeared in a "how to become a congressman" article.
The cartoon appears to be based on a photograph taken of the celebrity couple meeting the former president at a fundraising event in 2012.
In response to a tweet highlighting the cartoon, WikiHow replied: "Disgraceful. Working on preventing this from ever happening again."
The website later apologised for the cartoon, created by a team of illustrators in 2014, explaining: "The colourist wasn't aware it was Obama and Beyoncé."
Wikihow tweeted: "When we saw the whitewashed image of Obama, Jay Z & Beyoncé, we were disgusted & ashamed. It never should have been on wikiHow.
"Within minutes of the 1st tweet, a volunteer removed the image. We then started investigating how it got on wikiHow at all.
"We learned it was made 3 years ago by a team of illustrators who work as one. One person sketches, the other person colors.
"The sketcher sent the colourist a black and white sketch. The colourist did not know the race of the models."
It continued: "The colourist wasn't aware it was Obama and Beyoncé. We don't think the illustrator intentionally whitewashed here.
"This doesn't excuse the fact that we hosted a terrible image on wikiHow and we needed more diversity on that article period.
"We're talking with our illustrators to prevent recurrence and encourage diversity. Especially in positions of power."
