Gaga's such a tea-se

China in her hand ... GaGa and pal

LIFE is just mental for LADY GAGA.

She teased fans by taking to the stage in her undies during the Paris leg of her Monster Ball tour on Saturday.
Earlier in the day she was snapped in her car sipping her favourite tea from a china cup as she left her hotel with a lady in waiting.
The singer hits the UK this week for more tour dates, starting with Nottingham on Thursday.
