Nick Cannon enrols in Howard University

Nick Cannon is heading back to school after enrolling at Howard University in Washington, D.C.

The actor, rapper and TV presenter took to Instagram on Sunday (21Aug16) to announce his new endeavour by sharing a photo of himself posing beside a sign for the historically black college.

"YOU KNOW!!!!!," he captioned the shot, in which he was shown carrying a designer Louis Vuitton backpack. "#HU2020 My First Day as a Freshman!!! Howard University Class of 2020."

Mariah Carey's estranged husband has also revealed how he is flying cross-country to attend classes, after posting a picture of himself onboard a flight early on Monday (22Aug16).

"Turning these Airplanes into School Buses!" he quipped.

He has also been sharing a series of quotes about the importance of education online, adding captions like, "Been getting Money now its time to get Mindful!!" and "Money Power Respect... Education Over Everything!!".

It's not clear what Nick is planning to study at Howard. He graduated from Monte Vista High School in Spring Valley, California in 1998, before launching his career in the entertainment industry.

Nick is squeezing school into his already hectic schedule - he is currently juggling his roles as host of reality shows America's Got Talent and MTV's Wild 'N Out, while promoting his new single, If I Was Your Man.

The 35-year-old is also a father to five-year-old twins Monroe and Moroccan, who he shares with his soon-to-be ex-wife Mariah, who he is in the middle of divorcing. The former couple split in 2014 after six years of marriage.
