The on-again, off-again couple Travis Barker and Shanna Moakler continue their custody battle, once again drawing the general public into one of their infamous brawls after the police were called in on Monday and tweets began to fly.

It began when Barker went to drop the couple's two kids, son Landon, 5 and daughter Alabama, 3, off at Moakler's Rhode Island family home. Life & Style is reporting that the two got into a major blowout, with an insider saying, "He started screaming and wouldn't leave the kids with her."
