Katy Perry has expressed sympathy for a young man called Spencer who was 'catfished' into thinking he was dating the Firework singer for six years!

'I just think it’s really unfortunate and very sad,' she told The Morning Mashup on SiriusXM. 'My heart goes out to him.'

Katy found out about the guy's 'love' for her, which even included getting an engagement ring ready so he could pop the question, after being sent the link to the MTV episode of Catfish that aired last week.

Sympathetic: Katy Perry said it was 'very unfortunate and sad' that a young man had been duped into thinking he was dating her in a catfishing hoax during an interview on SiriusXM

On the show, Spencer revealed how he'd started communicating with a woman he knew as Katy Perry through a texting app and then via email.

But it turned out that she is really a Canadian called Harriet now living in London.

Katy said in her SiriusXM interview that felt sorry for him, and the fact he didn't realize he was being duped.

'People have dreams and people live in different parts of the world where not everything is so accessible. We live on the coasts and we get stuff in a way that some other people don’t get, and I feel bad for him,' she said.

In the end, the MTV show hosts had to take Spencer to England before they could convince him that his six-year romance was all a hoax.

Meanwhile, Katy is all loved up for real with actor Orlando Bloom.

The pair who have been dating since January recently enjoyed a summer vacation together in Sardinia.

And The Lord Of The Rings star, 39, is even rumored to be looking to settle down with the Rise songstress, 31.

People magazine has claimed Orlando wants to tie the knot with Katy and have more children.

He has a son Flynn, five, with his ex-wife Miranda Kerr, who is engaged to Snapchat founder Evan Spiegel. Katy was previously married to comedian Russell Brand.
