Christina Aguilera -- One Big Awkward Family

until yesterday, Christina Aguilera was sharing her Beverly Hills home with her son, her estranged husband and her boyfriend.

A moving truck showed up Tuesday ... we're told to take Jordan Bratman's stuff away, and none too soon.  We're told current BF Matt Rutler moved in weeks ago.

As one source connected with the threesome put it, "Thank God Jordan is moving out.  It was getting really awkward, but Christina was letting Jordan stay for the sake of Max."

After Christina filed for divorce Jordan wouldn't move out of the house, so Christina was staying in various L.A. hotels, but eventually moved back into the family home.

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

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. 

Christina Aguilera -- Exploited by Her New Man's Band

Christina Aguilera is the best thing that ever happened to her new boyfriend's band -- and they know it -- because they quickly plastered her name all over their website in an apparent effort to gain exposure. 

Right after the news broke that Matt Rutler was getting all cozy with Christina -- the guys from the Nate Mott Band posted Xtina's name and Matt's name all over the "Tags" section of their homepage -- hoping to increase the likelihood that anyone doing a Google search for those two will find their band's website.

But, it seems somebody wasn't happy with the coattail riding ... because the Christina-related tags have since been removed from the website.

Christina couldn't have been too upset -- because she accompanied Matt (below left) to a bar in Newport Beach, CA on Sunday to watch her new man jam out a few songs with another one of the guys from the band.
