The designer's 13-year-old son is one of the main stars of the British brand's three-minute festive film and celebrated the unveiling of the clip with his mum and younger brother Cruz, 10, at the flagship Regent Street store on Tuesday night (03.11.15).

Victoria - who opened up her Dover Street shop in London last year - praised the teenager in an Instagram post, sharing a photo of the three of them and writing: "So proud of Romeo!! He looks so handsome in the @Burberry festive film.Thank you Christopher Bailey x vb (sic)."

Romeo - who has been modelling for the brand since 2013 - arrived wearing the label's trademark check scarf with polka dots while his Burberry label mate Rosie Huntington-Whiteley sent pulses racing in a black lace dress and sexy thigh-high boots.

And prior to the party, the blonde beauty admitted she met Romeo when they both happened to be on a flight and he asked her for modelling tips.

Speaking on BBC Radio 1, she recalled: "I was flying from LA to London a couple of years ago and I got this little tap on my shoulder.

"He was so sweet, asking me questions and getting my tips on modelling, and then Brooklyn [Beckham] wanted a photo."

Naomi Campbell also stars in the film - which celebrates 15 years of 'Billy Elliot' by recreating a scene in which the protagonist jumps around - and wore a burgundy dress to the occasion, while Michelle Dockery, Liz Hurley, Paloma Faith and Dougie Poynter were also in attendance.

Other celebrities who feature in the film include James Corden, Julie Walters, James Bay and George Ezra.
