Caitlyn Jenner received backlash from rapper Snoop Dogg on Instagram Wednesday. The "Keeping Up With the Kardashians" reality star, formerly known as Bruce Jenner, was called a “science project” by the rapper. His comments come just days after Caitlyn revealed her name on the July cover issue of Vanity Fair.

The 43-year-old “Gin and Juice” artist insulted Caitlyn in a caption alongside a photo of Akon, where he discussed the “I Wanna Love You” singer’s project to bring solar power to people in Africa. "Shout out to Akon! He is about to supply 600 million Africans with solar power. Im [sic] really upset that this isn't major news but that science project Bruce Jenner is," he wrote. The photo included a caption with a link to his YouTube channel, GGN. Snoop hasn’t removed the post.

Caitlyn’s Vanity Fair cover went public on Monday, resulting in a flurry of both praise and criticism for the 65-year-old former Olympic athlete. Despite Snoop's comments, the reality star is now more popular than ever, with more than 2.42 million followers on Twitter.

This isn’t the first time Snoop Dogg has dished out insults via social media. He started a Twitter feud with fellow rapper Iggy Azalea in October 2014, posting photos mocking the 24-year-old “Fancy” singer and comparing her to Marlon Wayans from “White Chicks” and a woman with albinism, according to E! Azalea fired right back, asking why Snoop was bullying her. He eventually apologized to her via an Instagram video.
