Is my wife overreacting?

I am pretty close with one of my female coworkers. I am very fond of her. We have a lot of similar interests. She’s a pretty girl but there’s no romantic feelings there. I wouldn’t cheat on my wife either. She updated her profile pic on Facebook and I heart reacted it. My wife saw this and is now pissed. She thinks it’s inappropriate. My coworker is like a sister to me. I don’t see it that way. Is she overreacting?
