Looking to defend her recently fired little sister Ashlee, Jessica Simpson unleashed the fury on 'Melrose Place,' calling her sister's ex-show "crap" on Twitter.

Jessica -- who just two days before Ashlee's firing wrote "Everyone watch my sis on melrose place tonight," -- now rips into the show following Ashlee's dismissal. "CW catching up on MP. who writes this crap? i have had bad scripts to work with, but this? thank God my sister is amazing and got you some press," Jessica Tweeted.
