Hold the Dream Phone! Katy Perry's latest and greatest Throwback Thursday photo is literally a dream come true: a teenage Katy is wearing a shirt with the words "Pop Star" bedazzled on it. (I'm pretty sure I owned that same bedazzled shirt in, like, eighth grade -- I think we all did.)

The only thing missing from this photo is a set of color-banded braces and latest copy of YM magazine.

Katy Perry is still hot on the trail of her nostalgia-laden Pristmatic world tour, keeping the '90s alive and well with butterflies, smiley faces and yin-yangs galore up and down the east coast.
