one of them wrote a memoir about it. the other has never responded, and the reason the story holds up is that it was never about her.
the short answer
jennette mccurdy's 2022 memoir i'm glad my mom died describes resenting grande while the two co-starred on sam & cat, specifically because grande was permitted to miss shoots to record and promote her first album while mccurdy was not given the same latitude for film roles. mccurdy frames it as jealousy directed at nickelodeon's inconsistency. grande has never publicly responded.
what the memoir actually says
the passages about grande are short and specific. mccurdy writes that grande was frequently absent from set to work on yours truly, that the production wrote around it — on one occasion by putting her character in a box — and that when she herself was offered film work the same flexibility was not extended.
the moment she identifies as the breaking point is not a conflict at all. it is grande arriving on set cheerful having spent the previous evening playing charades at tom hanks's house. mccurdy's account of her own reaction is that she could not take it any more.
what it is actually about
the memoir is a book about an abusive parent and an exploitative studio system. grande appears in it as a contrast — somebody the same age, in the same building, whose circumstances were visibly easier, and whose ease made mccurdy's own situation harder to bear. mccurdy is explicit that the resentment was hers and that it was misdirected.
why grande has not responded
she never has, in four years, and there is a reasonable case that this is the correct answer. a public response would convert a memoir about somebody's childhood into a celebrity dispute, which is precisely what the book is not, and it would put her in the position of arguing with an account of somebody else's experience.
she did speak, in june 2024, about the wider subject: the nickelodeon years and the quiet on set allegations. she described reprocessing her own time there, called what had emerged devastating, and said the environment for young performers needs to be made safer. she did not mention mccurdy.
why sam & cat ended
the show was cancelled in 2014 after one thirty-five-episode season, at a point when it was performing well. nickelodeon has never given a full public account. reporting at the time pointed at contract disputes and on-set tension, and the memoir supplies one participant's version of the atmosphere. that is the whole of what is known.
