PAUL MCCARTNEY’COME TOGETHER,’ CELEBRITIES …Watch My Second-Straight Surprise Concert

Paul McCartney‘s pop-up gig Wednesday night was star-studded with a little help from his friends … ’cause the show brought out a strawberry field’s worth of stars!

The singer-songwriter played New York City’s iconic Bowery Ballroom after selling the place out Tuesday … and, ya gotta check out all the arrivals eager to watch the Beatles singer perform.

Robert De Niro and his baby mama Tiffany Chen led the charge — though it looks like it was past their 1-year-old daughterGia‘s bedtime. While Robert and Tiffany made it a date night, Emma Stone chose to focus on family rather than her man … bringing her mom instead.

Tom Hanks and Rita Wilson — two huge music lovers — made the trek out … and comedian pals Jerry Seinfeld and Amy Schumer got the chance to see each other too.

Among the others in attendance … Robert Kraft and his wife Dana Blumberg, Cara Delevingne, Anne Hathaway and her husbandAdam Shulman, Andy Cohen, and Steven Van Zandt, just to name a few.

Paul announced the second performance online at about 10 AM Wednesday … and, tickets reportedly sold out within the hour. Doors to the venue opened at 5 PM and the show kicked off at 6:30 PM.

Like we said, McCartney pulled a similar move Tuesday … so, keep your eyes peeled on his social media, in case he wants to pull off the three-peat.

Cause remember … money can’t buy you love — but, it can buy a ticket to see a living legend and proximity to some huge celebrities.
