Beyonce -- There's NO BEEF with Kim Kardashian

Kim Kardashian and Beyonce don't hate each other's guts -- despite reports -- in fact, they're BFFs.

There was lots of speculation this week following a story in which Bey allegedly confronted Kim at Jay-Z's recent Made in America event in Philadelphia -- asking Kim to stop posing for the cameras because she was stealing Jay-Z's spotlight.

Director Ron Howard was at the event too -- and according to reports, Kim approached Ron to cast her in one of his films ... another detail that allegedly pissed off Beyonce.

But sources close to Beyonce's camp tell us, there was no confrontation whatsoever -- in fact, when Kanye performed with Jay-Z at the event ... we're told Beyonce and Kim watched their men together backstage, laughing and hugging the whole time.

As one source put it, "They love each other -- they talk fashion, family, Beyonce's baby all the time."
