The Prudential Center in Newark, NJ looks more like Hollywood -- with massive stars pulling up like Megan Thee Stallion, who's set to take the stage with Cardi B later in the night to perform their brand-new hit, "Bongos."

Saweetie was lookin' pretty in pink while stepping into the stadium, and MTV's iconic Moon-person mascot even pulled up to the shindig with a snazzy bowtie! Demi Lovato also hit the carpet looking sleek in black.

As you know, artists like Miley Cyrus, Olivia Rodrigo, Taylor Swift, and Sam Smith are all dukin' it out tonight for a coveted Moonperson statue ... with many of them covering multiple categories.

It's been a female-dominated year for the VMAs -- Artist of the Year nominations went to ladies only, like Beyoncé and Shakira, while Ed Sheeran is the only guy gunning for Best Pop ... going up against singers like Pink and Dua Lipa.

BTW, there are 16 tracks up for the Song of Summer category this year, with 3 of them being from the "Barbie" movie -- go figure.

As we reported, *NSYNC is gettin' the boy band back together for a reunion at tonight's award show -- 3 members have been spotted in NYC over the last couple of days, and JC Chasez was pictured riding in a private jet.

A source connected to the group told us they'll be presenting only, and not singing one of their hits ... but it's gonna be an epic reunion nonetheless.

Speaking of performances, the ceiling will likely be blown off tonight with folks like Doja Cat, Nicki Minaj -- also the emcee for this year's event -- and Måneskin ... not to mention loads more musical acts as the night goes on.

There's also slated to be a big medley honoring 50 years of hip-hop -- similar to the huge performance at The Grammys -- featuring D.M.C., Grandmaster Flash and the Furious Five, LL Cool J, and more.
