Xtina's New Man -- It's Getting Personal

12/3/2010 8:12 PM PST
Christina Aguilera's new arm candy, Matthew Rutler, is skipping his band's gig this weekend ... yet showed up at LAX today with the blonde bombshell. Did he find a higher paying gig?

The Nate Mott Band posted on it's Facebook page on Wednesday: "Do (sic) to personal reasons Matthew Rutler our guitarist will not be able to perform at Twin Rivers Casino Friday Night."

Best "personal reason" ever.
