xtinasplithubby.jpg Talk about the domino effect! Christina Aguilera and her husband Jordan Bratman “have been separated for a few months,” a source close to the singer tells Us Weekly. The two have not yet decided whether they will file for divorce, but the source says they are now living apart, and "they will see how that goes.”

They source continued, “They were very much in love. But over the last six months, it became clear they were more like friends than husband and wife.” Aguilera and Bratman began dating in 2002, and they wed on November 19, 2005 in Napa, California. The couple welcomed their first son Max in early 2008, and the source added, “[Max] is their main concern."

The last time we snapped the duo together was on August 9, 2010, and we observed them sharing an affectionate hug and kiss after a lunch date. Over the past two months, we snapped Jordan and Max together and Christina out by herself, but had no idea that they were having marital issues -- we just figured Christina's busy shooting schedule for Burlesque was the reason for that.

When asked for a comment on the matter, Aguilera's rep told X17online, "No statement at this time." Uh oh! That's not exactly a denial...
