Last night, everyone's favorite reunited couple had dinner together for the fourth night in a row!

BUT, unlike the previous three nights, they didn't spend last night together! Is there trouble in paradise already?

After another session at the studio (where John did the walk of shame in the same clothes he wore the previous night), John met Jen for dinner at the Sunset Towers. He then went back to his hotel and headed over to Jen's Hollywood Hills pad, where he only stayed for 30 minutes, then left alone.

Did they fight? Did he need to get out of his nasty two-day-old clothes? Or did they just need a break?
