Let's talk about Chelsea Houska and Adam Lind. We don't know what the dealio is with these two, but they just can't get enough of each other — even when they're broken up and having babies with other people. Sigh!

This week on Teen Mom 2, Chelsea and Adam had a rare chance to spend alone time together at Aubree's preschool orientation, and you better believe they flirted up a storm. It was kinda cute in a "OMG NOOO" way, but also vaguely confusing. Chelsea and Adam don't exactly get along, and let's not forget about the fact that Adam's girlfriend, Taylor Halbur, was pregnant at the time of this interaction. What was he thinking flirting with Chelsea on camera?!

"So at the orientation there was definitely a lot of the flirtatiousness. And I don't know why, that was weird. I think it's 'cause we just hadn't seen each other for a long time," Chelsea explained during MTV's Teen Mom 2 Season 5, Episode 3 after show. "And I don't know. I mean, seriously, I never know what it's going to be like when he comes. Either he's nice like that — usually he's nice like that if him and his girlfriend are broke up, but if they're together then he's like an a—hole."

Chelsea said she was suddenly attracted to Adam because he was so different. "I don't even really know him anymore," Chelsea explained. "The fact that I don't really know him anymore, and also he looks so different, it's almost like I was with a different person … it's such a crazy feeling not knowing the person you have a child with."

Fortunately, Adam and Chelsea didn't get back together after their flirtatious interaction, and Adam is currently shacked up with his baby mama, Taylor (who is probably less than thrilled after watching this segment…).
