Beyonce - Concert NEARLY got jacked in Brazil.

Beyonce may be loved a little too much in Brazil ... a crazed fan pulled her off the stage during a concert Sunday night.

Miss Z was singing "Irreplaceable" when she started glad-handing people in the audience ... one dude got way too carried away.

It's like she took a college course in concert recovery ... 

Beyonce got back on her feet and killed it. She even told the dude who almost jacked her concert, "Nice to meet you ... I love you, too."
