Harvard Business School has denied admitting Blac Chyna to one of their online courses.

Chyna's alleged acceptance letter was shared online this week by TMZ, but Harvard is going full Mariah Carey and claiming "we don't know her."

The acceptance letter read:

"Congratulations! On behalf of Harvard Business School Online, I am pleased to inform you that your application has been approved for the Business Analytics cohort beginning May 29, 2019. We are excited to welcome you to the HBS Online community and are eager to engage with you in the coming months.

"The HBS Online team is confident that your participation throughout the course will be invaluable to your fellow cohort members. We look for to having you join us!"

But a rep from Harvard has shut down Chyna's claims:

"Harvard Business School Online has not admitted nor provided an acceptance letter to a person named Angela White," they said in a statement to TMZ.

Oh, dear. Is Blac Chyna back to her old tricks?
