REYNA FOSTER GIVES BIRTH TO ADORABLE BABY BOY

Since we found out Marvel sweetheart, Reyna Foster, was pregnant with Sebastian Stan's son back in March, we've been waiting patiently and excitedly for the little one to finally make an appearance. But now the wait is finally over and we couldn't be more than thrilled because of it.

A couple nights ago, the actress took to Instagram to post this picture of her newborn son:

The Instagram post was followed shortly by an adorable Twitter post from Sebastian, along with yet another picture of his and Reyna's son.

We have to say, though, that baby Theodor is absolutely adorable. Those of us here at E! are wishing Sebastian and Reyna both the best of luck in life.
