Miranda Kerr and Selena Gomez -- Well, This Is Awkward (PHOTO)

The Orlando Bloom/Justin Bieber/Miranda Kerr/Selena Gomez love square united in significant fashion during Paris Fashion Week and it was nothing but uncomfortable.

Miranda and Selena posed for this pic at the Louis Vuitton show and looked like they'd both rather be in a dentist's chair.

Their common bond is of course Justin Bieber, who is  currently banging Selena and was famously and allegedly banging Miranda after a NY fashion show.

As TMZ reported ... earlier in the day Justin was at another show when Miranda suddenly appeared and Justin literally hid behind Kim Kardashian's butt.

Meanwhile ... back at the ranch in L.A. -- our photog got Orlando Bloom out, who famously took a swing at the Biebs in Ibiza, and asked about Justin possibly stepping out on Selena for Kendall Jenner.

So complicated.
