Last month Paula Patton called a truce in her bitter custody battle with ex-husband Robin Thicke after their six-year-old son began acting out [click here if you missed that].
Looks like the truce is off...
On Thursday paparazzi caught a tense exchange between Robin and Paula in a Malibu park that ended with Paula in tears and the police showing up to intervene.
According to reports Paula showed up over an hour late for the custody exchange and then claimed their son did not want to go with his dad.
The police were called and the custody exchange was canceled this week.
