Katy Perry watches 'Coronation Street' and 'EastEnders' when she visits the UK

Speaking to fans at her show at London's The O2, she said: "I am obsessed with this country.

"I fall in love with the English very easily.

"I like to watch 'Coronation Street' and 'EastEnders'."

Katy also spoke about "going to the pub", "making tea" and "eating Heinz baked beans", but admitted one of her earliest memories of England wasn't a happy one.

She told the audience: "I have spent so much time in the UK ... from writing songs in Surrey to going to Topshop for the very first time.

"I was so excited ... I went to Oxford Street when I first came to London about 12 years ago.

"In the US Topshop wasn't open yet ... we had H&M but not Topshop.

"I went to pay and then my card was declined. I only had about $100 on it anyway but someone had defrauded me.

"It happens ... it was my first memory of London ... going to Topshop and leaving empty handed.

"I know poor me. Poor little pop star on the stage at The O2. Horrible."

Katy's comments come just days after Rolling Stones frontman Sir Mick Jagger made a quip about 'Coronation Street' serial killer Pat Phelan (Connor McIntyre) during the band's Old Trafford gig in the city earlier this month.

He told the crowd: "We went to the Northern Quarter. We went down the Curry Mile and I think I saw Pat Phelan. He was eating some papadums!"

Should Katy ever make a cameo in 'Corrie' or 'EastEnders' she wouldn't be the first celebrity to go from pop star to soap star.

Spandau Ballet star Martin Kemp portrayed Steve Owen in 'EastEnders' from 1998 to 2002 and Boyzone singer Keith Duffy starred in 'Coronation Street' as barman Ciaran McCarthy from 2002 to 2005.

Katy's rival Taylor Swift is also a big fan of the UK and was recently rumoured to be in the market for a £30 million home in north London.

Taylor has sold 50 per cent more tickets this month than Katy on resale site Stubhub. Fans wanting to see the two go head-to-head can visit the sites, where prices start from as low as £25 - £51 below average ticket price - for Katy and as little as £30, which is £76 below average ticket price, for Taylor.

Those unable to attend the concerts for whatever reason can sell their tickets on StubHub.
