Jessica Biel`s brother slams Justin Timberlake and his tequila brand

Justin Biel, who is said to have worked for the 901 brand until a few weeks ago, posted a couple of videos to his Facebook page in which he alleges Justin sabotaged the company by refusing to promote his own liquor.

Biel says: 'I've been waiting for [Justin] to do something with this f***ing brand - make a song about it, put it in a god damn video, hold it up, take some pictures, I don't care - just do something because we're dying on the motherf***ing vine here!'

He continues: 'Sales dropped drastically from last year... way to go sales team! Our distribution partners still couldn't give two f***s about the brand, repping Patron all the way, and giving us the ol' fist up the a**.'

Jessica's brother reportedly left the company on good terms, even though it doesn't seem that way in the video.

A representative for 901 tells TMZ.com: 'Justin Biel's video was intended to be one in a series of videos created by 901 Tequila employees (including the brand owner) as part of a larger viral marketing campaign slated for the end of December. It was released prematurely without our knowledge and prior to the final edit.'
