Sometimes, pop star fans are as creative as the artist themselves.

One needn't look any further than Tumblr for fans using their talents and skills as a way to demonstrate their love for their favorite musicians. Fan art comes in all shapes and sizes, as you can see below.

There are pencil-sketched portraits, like the ones we found of Justin Bieber and Katy Perry, that made us drop our jaws in amazement over how talented Beliebers and Katy Kats are and the attention they pay to detail. Others are more graphically and digitally designed, like this awesome rendering of Lady Gaga from her 'Telephone' video or Kanye West made out of words.

Here are some our favorite pieces of fan art. Enjoy!
