Chaske Spencer & Taylor LautnerChaske Spencer is buffing up his bod, hitting the gym six days a week, before he starts filming 'Breaking Dawn,' the fourth installment of the wildly popular 'Twilight' vampire franchise. The actor is ready to reunite with his wolf pack co-stars in Vancouver next month, joking that the guys have practically become a "boy band" at this point.

"We're kind of stuck with each other," he joked about bonding with his co-stars on and off set.

And as for Taylor Swift's musical apology to Lautner, Spencer admits his co-star is much better with the ladies than he is.
