Katy Perry will reportedly host the 2017 MTV Video Music Awards in Los Angeles on August 27. The “Roar” singer will also perform at the VMAs ceremony and compete for awards in five different categories, including Best Collaboration and Best Pop for Chained to the Rhythm.

Viacom global entertainment group’s head Bruce Gillmer told CNN, “We are excited to have Perry as the host and a performer at the 2017 MTV Video Music Awards.” He names Katy as the perfect singer and the best person to anchor this year’s show, which promises to be the most diverse and fun-filled in VMA history.

When did they finalize Katy Perry?

Perry returned last month with her latest album, “Witness,” which debuted at No. 1 on Billboard 200 charts. The announcement came ahead of her world tour for “Witness” -- her recent visual for “Bon Appetit" surpassed 110 million views in just two weeks. A report by The Music Universe reveals that Katy is the first performer to be announced for this year’s awards ceremony.

“I’ve trained with MTV in zero gravity. I am on a group text with Neil deGrasse Tyson and Buzz Aldrin,” Perry told Variety on Wednesday. The pop star is reportedly rehearsing as she wants to give her best.

She shares it on social media

The singer shared the good news on her Twitter Thursday night.

She has shared dozens of photos of herself to create excitement among fans. Perry also penned on Facebook “I’m working hard and ready to be your MoonWoman.” The news means Katy has joined the ranks of fellow chart toppers who have hosted the fête, including Diddy, Miley Cyrus, Jack Blck, Eddie Murphy and Bette Midler.

MTV nominations

CNN reports that MTV announced the nominees for the 2017 Video Music Awards on Tuesday -- a representative took to Instagram to share the news with the world. Lamar will compete for the newly created honor of “Artist of the Year” with The Weeknd and Katy Perry.

Bruno Mars, Ariana Grande, and Ed Sheeran have joined them in the same category, which marks the first year the ceremony will ditch the gender-specific awards.

DJ Khaled’s “Wild Thoughts,” Mars’ “24K Magic,” Alessia Cara’s “Scars To Your Beautiful,” and The Weeknd’s “Reminder” will compete against Lamar’s “Humble” in the “Video of the Year” category.

This year’s MTV Video Music Awards will air live from The Forum in California, on Sunday, August 27. To recall, 2016’s MTV Video Music Awards didn't have a traditional host. However, the Award Show only featured Jordan Peele and Keegan-Michael Key as main commentators.
