Has Jake Gone All David Beckham?

Is that Jake Gyllenhaal with a tat? Has the birthday boy treated himself to some body art to mark the fact he's just turned 27? Well, we caught up with Jakey on the set of his new movie, Brothers, in New Mexico and he was definitely sporting a tattoo on his neck. We suspect it's been done for the film. Then again, maybe the David Beckham craze is catching on and he's got a picture of Reese Witherspoon emblazoned across his chest.
