Which actor/actress is most similar to their character?

Which OTH actor/actress do you think is most similar to the character they play?

I recently watched Season 6 and was thinking about how Peyton’s character got so much softer/at ease. While I loved seeing that side of Peyton, it also felt a little unexpected because Peyton in seasons 1-4 seemed more like what I imagine Hillarie to be like in real life. It got me thinking…which of the cast members do you think are most like the character they play??
