Oh yes. Sorry got 2 very expensive and privileged nights out in 2 very expensive and very privileged venues mixed up. Poor poverty stricken Jack I expect her OH fronted her every timeYou're mixing up two Jack stories there. Jude Law was in the Groucho Club when he inadvertently blocked Jack's view of the TV screen prompting her to roar "SIT DOWN I NEED TO SEE bleeping REDCAR". This 100% happened.
At The Ivy, Jack leapt upon the piano and provocatively sang Common People at her fellow diners which 100% happened. Jack seems oblivious to this being a total fail. No one dining at The Ivy is trying to live like common people so we're not quite sure what point Jack was trying to make. Maybe one day she'll spot Camilla Parker Bowles down the chippy and can have another go at musical class war.
