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

12/3/2010 8:12 PM PST BY TMZ STAFF
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.
