Almost two years later, Romeo has reprised his role for the iconic British brand in a festive film titled From London With Love.
Romeo, who's now 12, attended a launch party for Christmas campaign at Burberry's Regent Street store on Monday night. Dressed in a tux paired with the brand's famous check-print scarf, he looked like a true pro. Of course, proud parents Victoria and David weren't far away from the young star.
The Beckhams were joined by Burberry's chief creative officer Christopher Bailey, who has previously said Romeo "stole the show" on set.
"He was an absolute dream to work with," Bailey said after working with Romeo on the first campaign. "Honestly, he is the sweetest. Genuinely. So well brought up. I've known Victoria and those guys for quite a long time; they are just lovely, grounded, gentle, well-mannered little kids."
Romeo stars in the film alongside France and Campbell again, as well as supermodel Cara Delevingne.
Clearly, as his dad David revealed two years ago, Romeo is "the fashion one" amongst his children.
"We used to try to dress them up, but now they want to wear their own things," David told Grazia in 2012. "Brooklyn will just wear his soccer shirts and T-shirts, but Romeo is the fashion one, so he'll go for skinny jeans and a vintage T-shirt and funny hats. One Christmas he asked for a pair of Spats shoes."
With three Burberry campaigns under his belt, it sounds like Romeo could be following in his mother's fashion footsteps.
And let's not forget - he's got his dad's good looks...
