An American man believed he was dating Katy Perry for six years, despite the chart-topping pop star marrying Russell Brand and dating several other celebrities during their time together.
The ruse was uncovered by the presenters of Catfish Max and Nev, who use their MTV show to uncover online scams and fake relationships.
The man, called Spencer, believed he'd been having an online relationship with Perry for six years, despite never having met her and only talking to her on the phone once.
"She's awesome. Katy's funnier than I am, she's smarter than I am. I don't know how many people give her credit for that, but she's very intelligent. Katy's full of life, huge heart," Spencer told the show.
