Is it possible for my emotions towards this celebrity to derive from being soulmates?

Well if both of you have a connection, your soul is involved. The truth is that this happens to people now and again. People are just attracted to each other at time when they feel ready to become a couple. Try your best to ignor this because it is risky, very risky. If it's meant to be it will be no matter what you do or keep from doing. Pray because it helps a lot and focus on being relaxed, educated, working and happy.
