It looks like Tom Brady’s son, John Edward Thomas, might soon have a little brother or sister!

The injured Patriot quarterback’s ex, actress Bridget Moynahan, was spotted visiting a California Medical Center this past weekend.

And she’s looking all kinds of plump in the middle!

Who’s the father this time????

Update: A rep for Moynahan assures us she “is not pregnant.”
