Alexandra as Kristen looked as if she and Mandy were sisters She was actually younger than Molly when they filmed S1 - same thing happened in 8 Simple Rules - Amy, the actress playing the middle child, was a few years older than Kaley who was playing the oldest sister Alexandra Kristen looks like a teen mom - got pregnant in school and has a baby From S2 when Amanda played her it was explained that going forward they needed the character to no longer be a teen, a mom going into her 20s as the child started growing up and going to school - more "momsy" Whether this was the real reason for firing and replacing Alexandra has been debated with fans The thing with Amanda Kristen is she looked too different from S1 Kristen and also acted different - she seemed much older and nothing like their sister, an aunt or a completely different character When Molly decided not to return as Mandy when they moved networks in the seventh season, we had lived with her as Mandy for so many years it was difficult to accept anyone as a "new" Mandy Molly McC didn't do a bad job as such - with the blond hair she looked different, like it was our Mandy with a new look, and acted different, older, more "evolved", we just all missed "our" Mandy Having Eve only being a recurring "part time" character in the later shows due to Kaitlyn pursuing her other projects - and was the only one of the five actress playing the three sisters who went on to have real solo success as a leading lady in her own films and shows Amanda Fuller did nude scenes in her films - full erotic naked group sex in Red White Blue 2010, nude in Creature 2011, full frontal in Fashionista 2016, and that shower scene in Orange New Black , being the only one of the five girls to do nude scenes She played Kristen from 2012 - 2021 being the longest serving "full time" sister She played Brittany Murphy in the bio in 2014 She did Orange New Black 2018 - 2019 .
