This man was CONVINCED he was dating Katy Perry for SIX years

When Catfish first came onto MTV, we were shocked by what some people can do behind their computer screens.

However, it was a good learning tool, and thought us to be more careful about talking to strangers online.

Yet, this man mustn't have got the message because for the past six years, he thought he was dating Katy Perry.

Yes, the world-famous Katy Perry.

Spencer Morrill was convinced he was in a relationship with the star, despite only speaking to her over the phone once.

He appeared on the show this week and told Nev and Max: "It was an immediate connection. A million 'I love yous' back and forth. It was pretty cool.

"I would like to meet face to face and see if there's a future here."

Spencer and the false Katy had been texting and emailing for years and he even made her an engagement ring which he said cost him "25 percent of his savings."

Oh, and that one phone call? That set him back nearly 300 quid.

As the show goes, Nev and Max did some digging and found out that Spencer was actually talking to a woman called Harriet from the UK.

Nev broke the news: "We've found the person you've been talking to beyond really any shred of doubt, and you still want to believe the thing that makes you happier. You need to know that you're not talking to Katy Perry."

When Harriet and Spencer came face to face she eventually apologised for her actions.

"I'm like genuinely sorry. I can't change what I did, but I understand that it was really wrong," she said.

Drama, drama, drama!
