She never ceases to amaze with her zany choices of outfit.

The Born This Way singer made her way to the Langham Hotel with a pine tree decorated with baubles and a star as a hat.

Attention to detail: Lady Gaga had chosen a playsuit which resembled the pot of the tree

She cryptically answered: 'When you're lying in bed and you have a Christmas secret.'
The songstress continued revealing how happy she was to be back in an arena, saying: 'This is a very exciting day for me. I haven't performed in an arena since February because grandma had a hip problem. So thank you for being my welcome back.'
In between belting out her tracks she told the audience: 'I have a very very rebellious spirit but when I get in trouble I tell them I was born this way.'

Chatting away to the child heavy crowd, she said: 'I learned something really special during all my time off. While I was gone, I learned I might have had my picture taken every day and people calling my name but I felt unfulfilled.
'I never wanted to be famous for no reason. I live for this moment when the spotlight hits my face. I get to watch you laugh at me and say I can't believe she said that.

Strangely pretty: Even though Gaga was playfully dressed as a tree, her make-up was done delicately to make her still appear glamorous

Anything for her little monsters: Gaga happily posed with onlookers whilst staying in character

'I want you to know that. I want you to know, I don't live for fame I live for this moment right now, the applause.'
Earlier in the day, the chameleon-like singer had stepped out in another look, wearing a wig of blonde dreadlocks and a starfish-print trouser suit with her black bra on show.
