For the past week, the 26-year-old Scorpion King 2 actor has been rumored to be replacing Taylor Lautner, 16, in the role of Jacob Black in the forthcoming Twilight movie sequel, New Moon.

In the book series, Jacob Black's physique drastically grows beyond his natural teenage frame.

Copon's Facebook page was recently adorned with the messages "Michael Copon is in a Twilight Zone!" and "Michael Copon is the older Jacob Black!"

This has riled up some Twilighters, TMZ reports...particularly the ones leaving comments on Copon's profile, such as: "He's [Taylor's] done all the hardwork and so deserves it," "I don't want you playing Jacob Black in New Moon :( because Taylor is perfect and you're a douche."

Meanwhile, according to Taylor Lautner, Michael Copon might be getting a bit ahead of himself.

On Wednesday, the original Jacob Black actor told MTV News, "I've been working out since the day we finished filming 'Twilight.' I just weighed myself today; I've put on 19 pounds. I'm guaranteeing [New Moon director Chris ] Weitz 10 more [pounds] by filming. I get to meet Chris on Friday, in two days, so I'm excited. I'm going to have lunch with him."

He'd better eat something high calorie.

As for whether or not he's been officially nixed from New Moon, Lautner clarifies, "I don't really know too much to comment on it. As far as I know, I haven't been told 'no' yet, so it's still all up in the air... I've heard a lot of good stuff about [Weitz], so I'm excited to meet him. I heard he's like a surfer dude, and that he's really laid-back and friendly. It'll be fun."

Perhaps it's in Michael Copon's best interests, safety-wise, that the Weitz-Lautner meeting goes well!
