Ashley Greene and Joe Jonas shared one last PDA-filled dinner date Saturday night before she returned to work on Breaking Dawn. Joe dropped Ashley off at LAX Sunday and hugged her goodbye as she regrouped with Twilight costars Kellan Lutz and Dakota Fanning. Kellan debuted a slick hairdo in Las Vegas on NYE while costars Robert Pattinson and Kristen Stewart celebrated overseas on the Isle of Wight in England. The entire crew will be back in the States this month as Breaking Dawn resumes filming, and tomorrow we'll have the chance to see Rob, Kristen, and Taylor Lautner at the People's Choice Awards. We'll be there streaming live from the red carpet and backstage — join our coverage at 4:30 p.m. PST and follow us on Twitter for exciting updates from the show.
