Amber Tamblyn - Amber Tamblyn Releases Angry Raps She Offered Tyrese

The Sisterhood of the Traveling Pants star played a practical joke on the Transformers hunk when he mistook her for Wiz Khalifa's fiancee Amber Rose online and tweeted a request to work with her in the studio.

Tamblyn used the case of mistaken identity to get some feedback on her awareness raps about women's issues such as domestic abuse and abortion.

She later apologised to Gibson for pretending to be his dream recording partner - but news of the ruse spread fast and left many fans keen to hear her raps.

Releasing the tracks online on Friday (16Mar12), she writes, "So many folks over the last couple of weeks have asked me to make these songs downloadable which I couldn't do because, while I made up the lyrics, the music was not mine. So I asked my friend Dan The Automator (of Gorillaz and Handsome Boy Modeling School) to write new music for each track and I re-recorded the vocals with some extra new Thugessness added to each one.

"Dan and I threw this together for you (very literally, over night) and we hope you enjoy them, Especially because 100% of their proceeds will go directly to The Respect Project, a brand new fund of the 501c3 nonprofit Write Now Poetry Society which will disburse grants to organizations who run creative writing workshops for women and girls and those working to end violence against women."
