Years ago I stumbled upon a horror movie with pale humanoid aliens and stuff, and one of aliens (towards the ending of the movie I think) pointed its finger at the main character's shirt or button then the main character's lifts her shirt to reveal that her stomach is now glowing. I can't seem to find again that movie, I think it's a pretty old movie but not that old. Early 2000s i think.. If anyone rings a bell, I would be so grateful!
