And with such a large female fanbase, it's no surprise that Jesse Williams has over half a million followers on Twitter.

In addition, Jessica Capshaw and Ellen Pompeo also have Twitter accounts.

Wait, I just saw a van that had "Topless Maids" written on it with a phone number accompanying it. Is that really a thing?
