Mars will join Adele, Lil Wayne, Chris Brown and Young The Giant -- all confirmed to perform some of their biggest hits.
VMAs executive producer Amy Doyle told MTV UK they were stoked to have Mars on the bill.
"We're thrilled to have Bruno Mars bring his exceptional talent to the VMA stage," she said.
"He is one of the most exciting live performers today, and with his artistic versatility, he will undoubtedly deliver a standout performance."
This year, Jonah Hill, Rick Ross, Selena Gomez, Seth Rogen and Kim Kardashian will all be presenting VMAs.
