Jared Leto and Johnny Depp are amazing! Jared Leto is s in a band called 30 seconds. To Mars, he recently released a song called "Walk on water" which is basically a protest to the current political administration, if you listen to the lyrics it's about how some people are fighting for the wrong things and we should fight for our social movements, at least that's what I've gotten out of it.
As for me, I like Billie Joe Armstrong (Green day), ,he's a good guy. He's bisexual himself and generally supports the LGBT movement. I also want to rock guyliner like he does, lol.
Laura Jane Grace is another good one, I've raved about her before but she's a trans woman in the punk band "Against me!, from interviews she seems very sweet and down to earth, she's also incredibly strong and a wonderful mother. I feel like she's still got a long way to go so I feel for her, but the entirety of her music speaks volumes in her struggle to be punk and push her way through tough things.
None of these people I identify with or feel similar to, though. I just like them a lot. I tend to identify with book or cartoon characters, in my case the big "oh" moment for me knowing I was a guy was seeing female-turned-male characters, in my case it was Natani from the serial webcomic two kinds and Haruhi from the anime Ouran High School Host Club
