Bella's 'Twilight' baby bump grows (exclusive)

First things first: Are you sitting down? Great, because we just got our hands on an exclusive new clip from "Breaking Dawn: Part 1," featuring Bella Swan (Kristen Stewart), Edward Cullen (Robert Pattinson), Carlisle Cullen (Peter Facinelli), and Jacob Black (Taylor Lautner).
The 15-second theatrical trailer preview opens with some familiar snippets: Bella finds out that she's pregnant, and the baby is quite the kicker.


The following scene is where the never-seen-before footage begins. We're back in Forks, Washington, and a worried Carlisle informs Bella that "the fetus is too strong and fast growing." Anyone who has read the "Breaking Dawn" novel knows what's coming next is not going to be a pretty sight, as evident in the quick cut to what the unusual pregnancy has done to Bella. In place of a mother-to-be glow, her complexion is pale and sickly, and the bags under her eyes indicate she's had very little rest since discovering she's pregnant. Edward tells Bella, "It's crushing you from the inside out." No wonder the poor girl looks completely miserable and distraught; that baby -- who's only getting bigger and bigger -- is literally killing her!
The Cullens aren't the only ones worried about Bella. Jacob and the rest of the wolfpack have found out that Bella's in trouble, and they're determined to rescue her from the vampires before she becomes one. "Get ready, we're coming for Bella," warns Jacob. But Edward isn't about to let the wolves take the mother of his unborn half-human, half-vampire child away that easily. "You're not going to touch her," he says. We hear werewolf growls and the clip ends with a standoff between the werewolves and the vampires. Once again, the fight over Bella continues.
