London, Dec 29 : David and Victoria Beckham, who are in UK for Christmas and New Year, got the chance to hang out with his sisters to celebrate Joanne's birthday.

The 36-year-old footballer and his wife, who live in Los Angeles for most of the year, joined the girls for a party to celebrate his sister's birthday.

From Joanne's tweets, it became evident that she had no idea that the famous couple had arranged the surprise dinner for his younger sibling.

She knew she was going to her favourite restaurant Roka, a modern Japanese place in the heart of Fitzrovia in central London.

"Turned up at my fav restaurant and can't believe my close friends and family was here !!!! Amazin !!! So happy," the Daily mail quoted her as tweeting.

The footballer was clearly delighted to see his sister so happy that he arranged for a group photo that he promptly posted on his Facebook page.

"Merry Xmas everyone.... just at my little sister Jo's birthday party tonight," he wrote.

Beckham was seen beaming in the photo with the birthday girl right next to him, and he couldn't resist acting a bit childishly as he put two fingers up behind Joanne's head.

Posh stood off to the side on the right in between two of Joanne's friends as someone captured the moment. (ANI)
