Kate Moss joined Babyshambles on stage at their gig at a club in Ireland Monday night, lending her lungs to a duet with boyfriend Pete Doherty. According to reports, she chugged beer and chain-smoked during their rendition of “La Belle et la Bete” and throughout the rest of the gig. Photos from the performance show Moss looking zonked, with coke boogers clogging her nostrils. Although Doherty had checked out of London’s Priory rehab clinic only hours before and drank water all night, it appears to be business as usual for the pair. While playing in Ireland, rock chick Moss has eschewed hotels and instead opted to bunk on the band’s tour bus. No new comment on the couple’s marriage plans. (Life Style Extra)
