Alec Baldwin, Arnold Schwarzenegger, Whoopi Goldberg and other major celebs hit the Big Apple on Tuesday night to celebrate the grand opening of Planet Hollywood.

And, what a party it was … Alec, Arnold and Whoopi were joined in all the fun at the newly reimagined PH venue in Times Square with Alec’s wife, Hilaria, 50 Cent, Pete Davidson, Liev Schreiber, Boy George and Melissa Gorga.

The place was packed to the gills — not just with stars — but also with photogs and ordinary people just out for a good time.

Check it out … Arnold and Alec chat it up with Arnold’s hand resting on Alec’s shoulder as Hilaria stands nearby.

In another clip, Alec, Pete and a third guy sit at a table with Alec talking intensely and throwing a left hook to make his point. Pete just laughs his ass off.

Cut to Alec stuffing his face with tortilla chips while jabbering with Pete. Then Whoopi poses for paparazzi photos with 50 and Arnold in a booth.

And there was much, much more … but you get the picture.

Before this funny kiddo turned into a television personality, he was just throwin’ on his coolest attire in Montreal, Quebec … bustin’ out the white sunnies and teaching himself how to whip up a tasty meal!

He moved to New York City and started auditioning for movie and TV roles … He’s definitely an expert when it comes to food and wine, so much so he has two cookbooks! You may see him on your screens with costar Jonathan van Ness.

Need one more clue? During the pandemic, he was on Martha Stewart‘s “Martha Knows Best!”

Summer may be a ways off, but Miami didn’t get the memo — one smokin’ babe was soaking up every inch of those sunny Florida rays, wearing next to nothing!

This sizzling rapper dropped a fire shot straight from the 305 … but we’re keeping their identity a mystery for now. Take a good look and see if you can guess who it is.
