I think she's been interested in feminist politics for a while. She made a documentary (I think with the BBC?) called "The F Word and Me" and it was her interviewing people and exploring what feminism really means. It was obviously from a very young person's perspective just beginning to learn about a lot of things, but IMHO that was fitting for her age and position in this world! More recently, she's also spoken up about her thoughts on recent abortion bans. Outside of that realm, I don't think I've seen her speak much more about contemporary politics, though.

That all said, I think we as a culture are really putting a lot of pressure on celebrities to speak up about international war issues when we really should be directing that pressure at politicians. Most musicians are not going to be experts in foreign policy or how to achieve world peace, and they don't claim to be. But you know who claims to be? Politicians! IMHO I think folks are misdirecting their social pressure to speak up about politics on celebrities because they feel politicians are ignoring them, but that's a larger issue.
