Flower Visual effect on sims head

This started after I brought my 2 sims back from a getaway so I don't know if that has something to do with it but they have this weird animated effect over their head, almost like how kids get when they're imagining something. I tried clicking on them to see if there was a way to disable it like there is with the fame shine from get famous but couldn't find any setting. I think its really annoying so was wondering if anyone know what's causing it or how to disable it? It only happens when I'm clicked on the sim.
