Christina Aguilera  singer hat lax airport boyfriend

Christina Aguilera and her boyfriend Matthew Rutler are still going strong!

The twosome cruised through LAX while making their way though crowds of her adoring fans ... and Matt held on tight to Xtina's bright red bag. Looks like the diva has trained him well.

The Voice judge and her beau met back in 2010 while she filmed the movie Burlesque in which Rutler was a production assistant. Now with Xtina's divorce from Jordan Bratman behind her, she's free to take the next step with Matt.

Can't wait to see if this relationship makes its way to the altar!
