Katy Perry feels bad for the sap who got duped into thinking he was dating her for 6 years -- but the way she reached out to him might rub a lot of people the wrong way.
Katy was on SiriusXM's "The Morning Mash Up" and the hosts asked her about last week's 'Catfish' episode ... where a guy from Tennessee thought he'd had an online relationship with Katy.
Check out the clip -- no doubt, Katy has compassion for him. It's just that the California gurl kinda sorta took a shot at folks in the middle of the country, and their access to pop culture.
Like we said ... she meant well.
