Cruz Beckham's online tirade against his big brother Brooklyn and his wife Nicola Peltz came on the heels of Brooklyn and Nicola asking the Beckhams to stop attacking them in the media ... TMZ has learned.
Sources with direct knowledge tell TMZ ... folks from Brooklyn and Nicola's camp reached out to David, Victoria, Romeo and Cruz in the past few weeks, asking them to stop talking to Brooklyn and Nicola if they were going to continue leaking negative stories about them.
