Kelly Osbourne emerged from a ten-hour drinking session last night looking a little worse for wear.

The Chicago star stumbled out of London hotspot Bungalow 8 after a sneaky few with Sheffield rockers, the Arctic Monkeys.

The 23-year-old showed up at the club after tying up her performing duties in her West End show, Chicago. 

The daughter of Ozzy and Sharon was snapped leaving the Cambridge theatre with a long-haired mystery man before heading over to the Met bar, where she knocked back a few vodkas.

According to reports Kelly left the Met bar and opted for 33-minutes of fun at Bungalow 8 before heading home.
