Brother-on-brother crime.

Cruz Beckham took a swipe at his estranged sibling Brooklyn Beckham’s shady World Cup commercial while attending the England vs. Ghana game with dad David Beckham in Boston on Tuesday.

On his Instagram Stories, Cruz posted a picture of himself looking down at his phone instead of watching the game from their suite, while David, 51, was locked in on the action on the field.

“Don’t worry it was during the advertisement break 🤷‍♂️🤷‍♂️,” the 21-year-old quipped in his caption.

In a DoorDash ad released in full last week, Brooklyn, 27, poked fun at his ongoing family feud by giving away World Cup tickets to a delivery driver.

“You’re probably wondering why I’m watching the FIFA World Cup 2026 from home. It’s not like I don’t have tickets,” he says in the ad. “Um, it’s because … it’s a long story.”

As Brooklyn hands off the tickets, he says, “These can go to someone else. Put them somewhere fun.”

Page Six heard Brooklyn was paid at least $1 million for the ad.

But Brooklyn’s estranged family, which includes his parents, David and Victoria, 52, and his siblings Cruz, Romeo, 23, and Harper, 14, allegedly didn’t find the commercial amusing.

“To do an ad based on estrangement from family as if it’s a joke, when his family is devastated and his sister and grandparents are inconsolable, is terrible,” a source told us.

Brooklyn blasted his family in a lengthy social media statement in January, accusing his parents of “trying endlessly to ruin [his] relationship” with wife Nicola Peltz, whom he married in a lavish Florida ceremony in 2022.

The Cloud23 hot sauce founder claimed Victoria hijacked the couple’s first dance in front of their 500 wedding guests.

Brooklyn and Peltz, 31, subsequently renewed their vows in August 2025 in a private ceremony.

The rest of the Beckhams, meanwhile, have put on a united front since their falling out with the couple.

This month, David was supported by Victoria and three of his four kids at his Hollywood Walk of Fame star ceremony and celebrated Father’s Day with them at a London pub.

But David and Victoria still included Brooklyn in their Father’s Day Instagram posts, which he is reportedly “fuming” over.

“He’s asked them to leave him alone and they just keep posting him,” an insider recently told the UK Sun. “He wishes they’d leave it and leave him alone.”

While Brooklyn reportedly told his family to contact him only through his lawyer, Page Six exclusively obtained photos of Harper attempting to visit her big bro at his LA home on June 12.

A rep for Brooklyn — who was not home at the time of his sister’s visit — accused Harper of staging the move.
