INF Daily just caught Christina Aguliera’s boyfriend Matthew Rutler returning to her house after posting $30,000 bail and picking up his impounded grey Ford Mustang – the same one car was driving when he was arrested last night. While Christina was let off on only $250 for public drunkenness, Matthew got a DUI for blowing a .09 on a Breathalyzer, and will likely have several future visits to court.

Word is starting to spread that Matt’s the cause of Christina’s recent downfall. We’re not sure we believe that… but he’s certainly been there for a lot of it.
