Beyonce and Jay Z enjoyed cocktails made from chicken bones on Friday (28.02.14).

The superstar couple wound down after performing together at Beyonce's sold-out concert at London's The O2 arena by visiting quirky pub White Lyan - known for not serving branded products - in trendy Hoxton, east London, where they sipped on unusual concoctions such as the Bone Martini.

A source told the Daily Star newspaper: ''They weren't shy about trying something different. The oddest thing they drank was a cocktail made with chicken bones called the Bone Martini. We thought Beyonce would be more reserved when it comes to that kind of thing but she was loving it.''

The 32-year-old star was clearly in the party mood after completing the first of six nights at The O2 and let her hair down with her entourage as well as Jay, 44, who had joined her on stage earlier in the night to perform their latest collaboration 'Drunk in Love'.

A source added to the Daily Mirror newspaper: ''Beyonce had a go at making some cocktails and danced the night away with hubby Jay and one of her stylists and some others.''

After a night of drinking, the couple - who have a two-year-old daughter, Blue Ivy - opted for a quick snack as they visited one of Brick Lane's famous bagel shops.

Beyonce's late night bagel binge comes a week after she treated her entourage to £700 worth of McDonald's fast food following her concert in Manchester.
