Jennifer Aniston Goes Conor McGregor on Fan's Phone ... for New TV Show

Jennifer Aniston went HAM on a fan trying to sneak a selfie vid with her on the street, but unlike Conor McGregor she won't be arrested for it ... 'cause it's all for TV.

Jen was shooting a scene for her new Apple TV+ show, "The Morning Show," in NYC Thursday night ... and it features her going off on a guy and snatching his phone.

Check it out -- Aniston unleashes an f-bomb rant and looks primed to punish the dude's phone, but fortunately ... Reese Witherspoon's there to talk some sense into her!

If only Conor -- or Offset for that matter -- had someone like Reese in their crew.

"The Morning Show" is an upcoming dramedy web television series starring Aniston, Witherspoon, Steve Carell, Gugu Mbatha-Raw and Billy Crudup. It's described as "an inside look at the lives of the people who help America wake up in the morning."
