Uh oh!

The police were called to Travis Barker's Calabasas home earlier this morning, and it was supposedly regarding a domestic dispute between the rock star and on-again/off-again wife Shanna Moakler. Travis allegedly made the call to 911, and we can only assume what happened behind the doors of their home...

Though the two got divorced a few years ago, they've been spotted out together lately, and all signs pointed to a reconciliation, but apparently that's not the case. A rep for the couple tells Us Weekly that they've split yet again, and a source added that they got into a nasty fight last night where Shanna was "freaking out and acting irrational" (hence Travis calling the cops).

Think this will last? Or will they get together yet again?
