I don't know! And don't disrespect her last name! It's not like she chose her last name to be Cosgrove. Don't make fun ok?
Miranda Cosgrove's last name is Cosgrove.
WHO EVER PUT DIS DUMB QUESTION IS STUPIDTHE ANSWER IS COSGROVE........................... SO STUPIDThat answer was given by User:Aquilizan. However, I dont think that question was stupid because if her mother's last name was Cosgrove, that doesn't mean that her father's last name was Cosgrove. His last name could've been Brynn. If her parents were to split up, her last name could've used to be Brynn. But, because her parents split up, her last name would have to be either Cosgrove or Brynn. And maybe, she picked to have her mother's last name, Cosgrove. This is just an example. Her last name is Cosgrove.And this is the same personI just wanted to say that it was also possible that Miranda Cosgrove was just her stage name.
