The Only Celebrity President Biden Follows on Twitter Is Chrissy Teigen .
Teigen often publicly criticized Trump on Twitter, prompting him to block her.
On Wednesday, she tweeted at Biden before his inauguration.
President Biden heeded her call.
As of Wednesday night, the @POTUS account was following 11 government officials and Teigen.
When Teigen found out about the follow, she could hardly believe it.
She also felt the pressure of being the only celebrity followed by @POTUS
