You know what was really awkward? When Adam Lind totally got his daughter Aubree's birthday wrong during this week's episode of Teen Mom 2. This beautiful moment happened when Adam and Chelsea Houska were getting their flirt on next to Adam's behemoth truck, and girlfriend seemed completely horrified by her baby daddy's absent mindedness.

Also, if you're having trouble believing that Adam would forget Aubree's birthday, here's a quick transcript of their conversation:

Chelsea: "I'm having her party on the 6th."
Adam: "The 6th? That's three days early!"
Chelsea: "Her birthday's on the 7th."

So, how did Chelsea react to Adam's memory lapse? After Kailyn Lowry tweeted "Did Adam really just get his daughter's birthday wrong?!" Chelsea shot back with a simple "righttttt."

Oh, and she also dished on the awkward moment during Teen Mom 2's after show, saying, "He didn't know her birthday! He knows it, I don't know why he did that or thought that. I couldn't believe he said that."

Yikes, guys. There's really no excuse for Adam getting Aubree's birthday wrong, but to be fair, it's possible that all that lawnmower riding has addled his mind. Bless his tattooed heart.
