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, popeater.com reports.

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.

Ashlee was fired along with Melrose’ co-star Colin Egglesfield last month. Show producer Todd Slavin told EW’s Michael Ausiello that “the tone of the show was going to shift into a much more fun, romantic, sexy upbeat kind of show,” and that Simpson’s character didn’t fit into those plans anymore.

Us Weekly, citing a set insider, claims that The CW “hired her (Ashlee) because they needed a good name to help create buzz.”
