The Beckhams were out in force last night (December 28th) as they banded together to celebrate David’s younger sister’s 30th birthday – almost two months ahead of the real date.

Victoria and David both wore designer watches as they posed with birthday girl Joanne, who according to Twitter, had no idea her celebrity brother was joining her for dinner at Roka.

It seems Victoria was wearing a ladies designer watch around her wrist, which complemented her black ensemble and trim hairstyle.

While the children were nowhere to be seen, David looked as handsome as ever in a designer watch, knitted jumper and white shirt.

Joanne also paid tribute to accessories, as she inspired women in search of online jewellery with her ladies designer watch and two gold bangles.

The soon-to-be 30-year-old posed with brother David at the restaurant table, both wearing similar smiles that compounded their family unity.

Joanne tweeted: “Aww turned up at my fav restaurant and can’t believe my close friends and family was here !!!! Amazin !!! So happy.

“My bday is feb 19th and I will b 30 but we celebrated early jus in case y big bro wasn’t here !! Had a amazing nite [sic].”

The younger Beckham, whose blonde locks were flowing, posted pictures of the party on the micro-blogging site, showing an impressive celebratory cake in the design of a cupcake, with pink and white icing.

Describing herself as a “lucky girl”, Joanne seemed to be delighted her brother and Victoria turned up to make a fuss of her ahead of the New Year.

Becks is set to take his footballing talent back to European soil when he signs up with Paris Saint-Germain in January for an 18-month contract.

The move could boost the star’s monthly balance by £700,000, making him France’s most well-paid athlete.
