Who are the people she is singing to in 'Back to December' and 'Mean'?

back to december is Taylor lautner and mean is about girls in high school apparently

You're probably right about Back to December, but I think I read somewhere that Mean was about someone who bullied her.

I think the song about Kanye is "Innocent".

back to december is about taylor lautner but mean is a bout a bully she had in her life and in other peoples lives.

i think that mean is when she had a boyfriend and he was not nice to her calls her names and stuff and then back to december i have not seen that in so long that i dont know

Back To December is her apologizing to Taylor Lautner about their breakup and how she misses him. It also mentions Kanye in the line 'And how you held me in your arms that september that night, the first time you saw me cry'. Shes referring to when Kanye made her cry at the MTV awards and Taylor comforted her backstage :)
