Kylie and Tyga -- We're Engaged ... Or Maybe Just Engaged In Foolery

Kylie and Tyga are finally ready to tie the knot ... at least that's what one video suggested -- but Tyga might've just been brushing up on his impressions.

Kylie posted a video to her Snapchat on Wednesday of her bf Tyga and it sounds like he says, "I don't f*** with nobody, it's just me, my fiancée, this lil' dog I just got" ... making it seem like he and Kylie are engaged.

However, if you dig a little deeper -- Tyga posted a video earlier in the day of an old interview with rapper Logic saying almost the exact same thing.

So we're callin' shenanigans.
