Is it weird to tell someone you know that you saw their profile on a dating site?

There’s this girl I used to work with that I’m decently good friends with. Even though she just recently stopped working at the same place we still send each other stuff on Snapchat pretty frequently. The other week out of nowhere I was kinda going through hinge and I saw her on there lol. Is it weird for me to tell her I saw her on there? It would just be something random like “hey I know this random but I saw you on hinge the other week lol”. Is it weird or is it fine?
