Elizabeth Berkley doesn't speak out too often these days, but when she does, it's for a good reason. The former Saved by the Bell [1] star took to Twitter yesterday to defend Christina Aguilera [2] after a gossip blogger made a disparaging comment [3] about the singer's baby bump.

But Berkley didn't stop there. The actress continued to tweet throughout the day, asking all people — not just members of the media — to change the way they talk about pregnant women. She even called on friend and former model Christy Turlington for support [4].

Now this is a change we can get behind. What about you?
