This is freakin' hilarious. Is Krista the one behind it?
Not Krista but this is an official Telenext Twitter account so someone associated with the show is behind it.
It's the same Twitter account they had Mindy using during the class reunion storyline. ATWT's Molly is also now on Twitter, obviously leading up to her return to the show.
This is a nice way for fans to stay connected to the show. It's also damn cheap.
