Who is Tracy Romulus, Kim Kardashian's chief marketing officer?

Tracy Romulus, one of Kim Kardashian's closest confidants, is also her right-hand when it comes to marketing.

Romulus, 42, has been working alongside Kardashian, 41, since the beginning in 2017, as the reality TV star launched all three of her businesses under the KKW Brands umbrella. Romulus' music-producing husband Ray Romulus, 39, has also worked with Kanye West, 44, on recent music.

However, West seemingly has issues with Romulus. In a social media post shared Friday, the rapper accused the PR guru of "manipulating" Kardashian. 

Even before Friday's post, West has publicly shared his dislike for Romulus. While opening up about Kardashian's appearance on "Saturday Night Live," West seemingly threw shade at Romulus.

"Working for Kelly was an incredible learning experience," Romulus told People magazine. "It was a tough love kind of boot camp. Kelly literally threw me to the sharks and told me to figure it out, and I did. I made a ton of mistakes along the way and probably cried a lot, but everything I learned during those two years of working for her had the most impact on me."
