Wrong number?

Lily

So tonight as my SO and I are watching Netflix in bed his phone goes off at midnight. We both look at at and it’s a text from some girl saying “hey Greg, we met on tinder and I went out of town but I’m back now and want to meet up” with a picture of her topless... now, my SO’s name isn’t Greg, BUT... like WTF? He’s of course denying everything, but part of me is wondering if he has a fake profile on tinder... or maybe it’s really a wrong number? I just don’t feel like girls text naked pics unless they know the person... HELP
