Once a year, the MTV Video Music Awards roll around to honor a year's worth of work in music videos.

This year, the show will take place in Brooklyn, New York at the Barclays Center. The event will air live from the venue, the network announced in June.

Since the show, which takes place on Sept. 12, is so close to the 20th anniversary of the Sept. 11, 2001, terrorist attacks, MTV has teamed up with "the 9/11 Day nonprofit on events designed to ‘promote awareness and action’ in honor of the National Day of Service and Remembrance."

Sure to be an evening packed with stars, memorable performances and more, here's what you need to know about the 2021 MTV VMAs.

The 2021 MTV VMAs will air on MTV on Sept. 12 at 8 p.m. ET. It has not yet been confirmed this year, but in the past, the awards have also aired on a few other ViacomCBS-owned stations such as MTV2, VH1, Comedy Central and The CW.

For those who prefer streaming, the VMAs will be available on the MTV app, on MTV's website and on Paramount+.

This year, singer-rapper Doja Cat will serve as the host of the show.

The "Say So" musician, 24, announced the news on Twitter in August. According to Billboard, this will be the first time in history that the host was nominated for video of the year that same year.
