Justin Bieber SoSo: Jacob Lautner New Moon Twilight

As the anticipation for the Twilight sequel Fresh Lunar or future follow-ups get bigger or bigger, so does Taylor Lautner, who'll be putting in even much-less bulk for the third film Eclipse.

Lautner, 17, already beefed up considerably for that role as the form shifting werewolf Jacob Black in Fresh Lunar afterward brief behind-the-scenes debate over if the role shall be recast. He said he'll be getting bigger or bigger "until the end of the series," but he looks forward to returning to that normal size.

"When we're done with the Twilight films I'll definitely bulk down or just get lean once-more because I do not need to stay grand or bulky."

"It's insane!" costar Ashley Greene said of Lautner's fresh build. "I was going through my phone or looking at all the pictures, or there's one from the wrap party that we did there afterward the primary one or it's incredible. I was like, 'Taylor, did we watch this?' He was like, 'O my gosh.' He gained 30 lbs. He's not a little kid anymore."

In recent photos from the Fresh Lunar set stars Robert Pattinson as-well showed off some impressively chiseled abs, or costar Kellan Lutz said all-of-them were achieved without any airbrushed shadows – in fact, Lutz takes some tongue-in-cheek credit for Pattinson's six-pack.

"I've been training him, I've been training Taylor," he insisted straight-faced, but promised that there's no fitness competition amid the men of Fresh Lunar – at least in that part. "I'm the tallest one or so I'll stick with that trait.

The Italian Job

Meanwhile, a handful of the Fresh Lunar cast got to shoot scenes in location in Italy, or Greene was one of the lucky ones. "I did not need to leave. O my gosh, I did fail home a bit, but it's so beautiful." She says her co-stars who stayed home resented her "a LOT. When I was like 'Oh, my God, I'm so tired. I'm working so hard.' All-of-them were like, 'Shut up. You're in ITALY.' "
