Please face plant into a slice of cake, because Aubree Houska's birthday is upon us. This little lady celebrated her fourth birthday during this week's dramatic episode of Teen Mom 2, and you know what that means. Her mom, Chelsea Houska, had to actually interact with her baby daddy, Professional Facial Hair Grower/Victim of Tattoo Experimentation, Adam Lind.

Aubree's birthdays have been a source of contention for Adam and Chelsea in the past, and this year was no different. Actually, it's majorly different because Adam's baby mama, Taylor Halbur, popped out his latest love child during Chelsea's recent trip to Los Angeles, and homegirl was extremely worried about the impact this little lady's arrival could have on Aubree. Apparently, Chelsea doesn't want Aubree to have half-siblings from Adam's side of the family — which is slightly unfair, but who can blame her.

The strange thing? Despite Chelsea's issues with Adam, we sensed some major sexual tension between these former love birds when he popped by to wish Aubree happy birthday. Maybe Adam was just high on the fumes of baby-making, but these two were kind of adorable together. Just like one big, flawless family … with another flawless family on the sidelines.

Sure, there was some tension when Adam tried to steal Aubree away from Chelsea, but then they fist bumped in the cutest way ever and we were just like (in the words of Fergie Ferg), WHERE IS THE LOVE?

Do you think Adam and Chelsea were surprisingly flirty on Aubree's birthday? Weigh in below!
