Travis Barker and Shanna Moakler split again. The break up of Barker and Moakler reportedly comes after …

… “a nasty fight broke out at his house last night and cops were called…[when] Shanna started freaking out and acting irrational.”

The two are confirming the official split today. Reports, which Shanna denies, claim:

“Travis confronted Shanna about her having an affair with Gerard Butler while he was in the hospital recovering.”

Will break up #2 be for good?
