Nothing was keeping Teyana Taylor down last night! We caught up with the actress right after her tense confrontation with Oscars security … and she was determined not to let it ruin her night.

Teyana downplayed the interaction, saying, “Security was just doing a lot … There’s always that one.”

ICYMI … moments after joining her “One Battle After Another” cast onstage to accept their Best Picture statuettes, Taylor was stopped by a security guard who put his hands on her.

Video from the night shows Teyana going OFF on the guard, and she explained to us, “I just don’t tolerate disrespect — especially when it’s unwarranted and it’s unprovoked.”
