Kelly Osbourne might need more than one key for the door to her family's large mansion and other far-flung bolt-holes.
The wild child came of age and celebrated her 21st birthday in true Ozzy style by treating friends and family to a night on the lash.
Kelly partied with celeb pals including Kate Thornton, Nicole Appleton, director Ron Howard and his daughter Bryce Dallas Howard at London's Sketch club.
And mum Sharon even invited several contestants from the X Factor, making for quite a mixed bag on the big night.
While we wish outspoken Kelly a very happy birthday, we hope that the big 21 won't see her becoming all sensible and mature.
Raise your glasses too and join the party - in a virtual-style - with a peep at the pics in our gallery.
