The name too, is very similar. Sure you can say it resembles Celestia but that's not exactly official information. I do kinda think that the design was intended to resemble Celestia, and Alex just kind of took the question as what the unicorns were originally based off of.

On the topic of Gravity Falls/MLP one of the comic creators added Mabel (sorry, I bring this up a lot but I just thought it was cool lol)
