Selena Gomez & Miranda Kerr -- When (Alleged) Eskimo Sisters Meet ... (PHOTO)

Selena Gomez and Miranda Kerr came face-to-face and cheek-to-cheek ... and given their history, it could have been a tad AWWK-WARD.

Quick check of the scorecard -- Gomez and Kerr allegedly hooked up with each other's exes ... Justin Bieber and Orlando Bloom ... which allegedly led to Orlando taking a swing at Justin in Ibiza last summer. They all deny the allegations.

Now cut to Wednesday in Palm Springs where Miranda and Selena seemed totally cool with each other at a Louis Vuitton event. Sure, they could be faking it ... but we've seen them hang before -- at another LV gathering.
