Ashley and Kellan signed on for Breaking Dawn

An article at EW says Ashley and Kellan have now made deals for the Breaking Dawn movies.
Below is what they say:
Ashley Greene and Kellan Lutz, two of the Twilight co-stars that were in a heated battle with Summit Entertainment over the deal points for the fourth and fifth installment of Breaking Dawn, have signed their deals, sources say. It’s not clear which party buckled and both sides are sure to have their spin, but we can confirm that we’ll see Green back as Alice Cullen for the last two Twilight films. And hunky Lutz will also return as Emmett Cullen for the conclusion of the epic franchise. Bill Condon is directing and production is set to begin in the fall. Summit Entertainment would not confirm the deals.
