Remember last week on Teen Mom 2 when Chelsea Houska's baby daddy Adam Lind got Aubree's birthday wrong? Well, looks like this dude is suffering from a serious case of ex-boyfriend amnesia because this week he forgets Chelsea's birthday! Why does this not surprise us?

In this sneak peek clip of Tuesday night's all-new episode, Chelsea and Adam meet up for Aubree's pre-school orientation. On their way inside, Chelsea asks a couple of probing questions to try and jog to his memory — unfortunately to no avail.

"Do I look any different? Do I look 22?" she finally asks.

Adam's response? "Oh yeah. Happy birthday."

What can we say? At least he bothered showing up in the first place. Plus, he seems to have discovered these things called sleeves. Baby steps, people.

As for the orientation, things stay relatively amicable between the pair (last week's flirtation seems to be over, thank god), who both hold hands with Aubree on their way out. But this image of the perfect family doesn't last for long — when they get to the parking lot Aubree must give her dad a hug and say goodbye. Fortunately, this adorable munchkin doesn't seem too fazed. She must be too excited about that super cool Disney princess backpack she's rocking.

Check out the sneak peek clip and tell us what you think of Adam's faux pas below. And don't forget to tune in Tuesday, February 11 at 10 p.m. ET on MTV.
