The Beckhams Cheer on Romeo in the Junior London Marathon

When it comes to attending big fashion and sports events, the Beckhams like to turn out in force, and this weekend they had extra cause to show a united front, as 12-year-old Romeo Beckham took part in the kids' division of the London marathon. Mom Victoria, dad David, and brothers Brooklyn and Cruz parked at the sidelines to play cheerleaders.

Romeo was among the 11- to 17-year-olds who ran a three-mile version of the annual London marathon and proved how he takes after his sporty father by completing the course in an impressive 18 minutes. He also raised £6,000 ($9,071) for charity.

The family showed their support by waving handmade signs and were also decked out in matching "Team Romeo" T-shirts. And his mom was sure to show off her son's achievement by sharing a snap of the family's posters and writing that she was "so proud" of her boy:

Big brother Brooklyn also took to social media and revealed the team tees in all their glory:

Congratulations, Romeo!
