I don't think so. For one thing she's recording it, and another thing, he's not wearing his glasses. If he's not wearing his glasses around Lois, she already knows.
Based on the dialogue--"you have a dog?"--it seems like she just found out. They're definitely friends and attracted to each other in that scene but it is hard to tell if they are a couple. In fact, it looks like they're just friends or they've just begun dating.
