Using Divine Smite as a duel-wielder

Divine Smite allows my Paladin to expend a spell slot to deal extra damage after landing a melee attack. My character wields two swords. Since Divine Smite isn’t a bonus action (because the rules don’t say it is), I can use my bonus action to attack with my second sword while also using Divine Smite. So, providing both attacks land and I have two spell slots to use, can I use Divine Smite twice?
