Shawn Mendes just hit on Hailey Bieber and Justin Bieber made it awkward

Those Met Gala photos didn't happen for no reason!!!

But, since Hailey and Justin Bieber tied the knot, Shawn has been nothing but respectful and happy for her. He DID however once state that she was the one that got away...

So, when Justin posted a gorgeous photo of Hailey recently, and Shawn 'liked' it, fans lost it.

So much so, that Hailey's husband had to intervene. Thankfully, Justin didn't show his jealousy. Instead, he told people to relax.

"Their (sic) friends relax," JB wrote.

Oh, that's awkward.
