Revenge of the Pop Star

How many girls who were shunned in high school wish they could do this?

Katy Perry got her own back at her teenage crush when she spotted him at a surprise concert at her high school yesterday.

The 25-year-old singer was performing to past and present students at Dos Pueblos High School in Santa Barbara, California when she spotted former classmate Shane Lopes in the crowd.

While Perry is probably having the last laugh being a millionaire pop star, she took the opportunity to chastise him for turning her down.

During a break between songs, Katy said: 'Is that Shane Lopes?

'You were the most popular kid in my class! But you never wanted to date me, it was always Amanda Wayne.

'Oh yeah, you really chose right honey. What’s up. What’s up now, player. I’m going to dedicate this next one to Shane Lopes everyone.'

She then embarrassed him further by dedicating her song Ur So Gay to Lopes, who was a quarterback on the school's American football team.

Toby Keith did a song a few years ago with a similar theme - "How Do You Like Me Now?"
