There have been spreading rumours that pop star Katy Perry had to be carried out of a London club at 5am during Justin Bieber's party

The two have played for the Capital FM Summertime Ball right in Wembley and after a lot of partying, the 'Part of Me' singer suddenly had to depend on bodyguards and her other friends just to help her stand.

A close source told the Daily Mirror that Perry became very excited upon learning that Justin Bieber was there and that she adores the young pop star so much. She also found time to catch up with another good friend, Jessie J.

More information relayed that Perry already had a few vodka cocktails during the early parts of the day. She was spotted having huge bottles of Ciroc and Belvedere Vodka and that by 5am, she was seen wobbling while walking and just fell to the floor. It caused a commotion and even Max George of The Wanted helped to carry her.

Well it is quite normal for celebrities to get high in spirits sometimes and easily get drunk during the parties they attend in. But when the booze just gets all too much, it brings them to more shame than they can imagine. At the end of the day, it still gets forgotten reminding everyone they're just as human as everyone else.
