‘Jersey Shore’s Angelina Serenaded Onstage by AJ McLean & Joey Fatone

Angelina Pivarnick lived every millennial’s dream by joining Backstreet Boys’ AJ McLean and *NSYNC’s Joey Fatone for a show … and yes, she rocked out like any of us would.

TMZ has obtained video featuring the “Jersey Shore” star enjoying a boy band-filled gig in Newark, NJ last week … where Joey and AJ teamed up for a concert at the New Jersey Performing Arts Center, and where Angelina was front and center as a megafan.

It seems her adoration for the fellas paid off … ’cause they brought her onstage to sing and dance … and she did plenty of both.

Angelina proved she’s just like any other Backstreet/*NSYNC fangirl — boldly belting along to the duo’s rendition of “It’s Gonna Be Me” … happily filming selfie videos with fellow fans, too.

Folks are feeling as nostalgic as ever on this front … especially since *NSYNC recently reunited onstage during Justin Timberlake‘s free, one-night-only concert in L.A. earlier this month. The group performed their new collab, “Paradise,” which is featured on JT’s sixth studio album … and it’s left diehards pining for a straight-up real reunion.

Of course, when we caught up with Joey at LAX recently, he kinda shut down any notion of a reunion happening anytime soon … making it clear no new album is coming from *NSYNC.

In the meantime, Angelina was able to get her fix here … and she ate up every moment!
