In Life & Style now: Twilight's hot hookups: back on!

The cast members of Twilight have promptly reheated their on-screen passion on the set of the movie's sequel, New Moon. "We went through a lot together, so we feel very close," says Kristen Stewart about her co-star Robert Pattinson. But it also seems like more than mere friendship as Kristen blushed uncontrollably when asked about kissing Robert at a recent news conference. "We all get along so fantastically, and we all have such great chemistry," co-star Ashley Greene, who plays Alice Cullen, told Life & Style.

But with Robert taking a smaller role in the sequel, new leading man Taylor Lautner (Jacob Black) threatens to divide this cozy twosome. "Jacob and Bella are best friends, and I know Taylor takes it very seriously in terms of forming that connection with Kristen and making sure that it's authentic," Rachelle Lefevre, who plays villainous vampire Victoria, tells Life & Style. "I don't think he's competing with Rob; I just know that he's going to be sure that his relationship with Kristen is just as intense and has just as much chemistry."
