Angelina Pivarnick lived each millennial’s dream by becoming a member of Backstreet Boys’ AJ McLean and *NSYNC’s Joey Fatone for a present … and sure, she rocked out like all of us would.

TMZ has obtained video that includes the “Jersey Shore” star having fun with a boy band-filled gig in Newark, NJ final week … the place Joey and AJ teamed up for a live performance on the New Jersey Performing Arts Heart, and the place Angelina was entrance and middle as a megafan.

It appears her adoration for the fellas paid off … ‘trigger they introduced her onstage to sing and dance … and he or she did loads of each.

Angelina proved she’s similar to every other Backstreet/*NSYNC fangirl — boldly belting alongside to the duo’s rendition of “It is Gonna Be Me” … fortunately filming selfie movies with fellow followers, too.

Of us are feeling as nostalgic as ever on this entrance … particularly since *NSYNC lately reunited onstage throughout Justin Timberlake‘s free, one-night-only live performance in L.A. earlier this month. The group carried out their new collab, “Paradise,” which is featured on JT’s sixth studio album … and it is left diehards pining for a straight-up actual reunion.

In fact, once we caught up with Joey at LAX lately, he kinda shut down any notion of a reunion occurring anytime quickly … making it clear no new album is coming from *NSYNC.

Within the meantime, Angelina was capable of get her repair right here … and he or she ate up each second!
