Justin Bieber lost his cool under oath Thursday, when a lawyer started peppering him with questions about Selena Gomez ... TMZ has learned.

The lawyer started asking if Selena was present during any incident involving fights with photogs. Bieber's lawyer, Howard Weitzman, felt the lawyer was just trying to get a rise so he objected. But the lawyer persisted and asked again ... Bieber was fuming and Weitzman jumped in and said his client was being harassed.

The photog's lawyer asked about Selena again, and at that point Justin and Weitzman stood up and left, and as Justin was leaving he screamed, "Don't ask me about her, do not ask me about her!"

Five minutes later they returned but things got even hotter. At one point Bieber responded to a question with the word "Yeah." The lawyer said, "Do you mean yes?" To that Bieber responded, "What the f*** is the difference between yeah and yes?!"

go to jail plz

yeah.

Yes pls!

What a diva

He is a trainwreck but I wouldn't love him if he changed.

Punk who doesn't even know how to behave in court. If you're there, expect them to be ruthless with you and go in for the kill.

He should've said YAS just to be clear.

he's so sprung off of her

she must've had that good good

But he should've just been a grown up and answered the questions about Selena. This is the government you're talking to, not GQ magazine.

why was the judge even asking him about her?
sounds like the judge was acting like an a** tbh

I would have said the same thing tbh.

Giving me Gaga in court teas.

Mess

This gif will never get old.

ugh

me too tbh
