I already have a work crush before even starting my new job?

Ok so I finally got a new job in my field yay! And when I flew out to tour, I was introduced to a girl I’ll be working closely with and she seems like she knows how to run things tbh and kind of led the meeting that I sat in on and even had a bit of a dry sense of humor. A little later I was personally introduced to her by my new boss and she blushed so hard when I walked up and was introduced and kept playing with her hair and did seem kind of nervous which was interesting given that she had led an entire meeting and her and I ended up talking for a while about crime in the area and she briefly mentioned her me her boyfriend had an incident where their car got broken into, so yeah she has a boyfriend. She seemed very very nervous when I walked up and was playing with her hair and skirt. This is my career and she’s in a relationship so I’m definitely not trying to jeopardize anything, I just feel like the fact that she could be so on top of things around everyone else and nervous around me made me curious lol. She was also really nice and helpful. She came from an even more impressive and intimidating role as a director and we’re around the same age ( early to mid 20s ). What should I do about this?
