Late night, Batman?

Ben Affleck hit the studio this morning looking as if he hasn't showered in days, and he's either burning the midnight oil now that he's a bachelor, or he's just totally given up. His messy curly hair and five o'clock shadow is bad enough, but he appears to have gained weight now that he's not beefing up for an action role.

Jen Garner should actually be happy to see these photos, because we highly doubt he's going to bag another Hollywood beauty looking this haggard!
