oil in radiator

[nmp57048]

I have had over heating issues the past week and found out that i need a new thermostat(the one that goes in the intake manifold) and i replaced that and started looking around it and i have a huge oil leak somewhere......i decided to drain the radiator and found out that now i have freaking oil in it does anybody know why this is? My worst thought is it could be a blown head gasket but i have no clue otherwise can somebody help
