Looks like Christmas is not yet over for Britney Spears -the singer recently wished the crowd at her Washington DC gig "Merry X-Mas".
The 'Womaniser' hit-maker has already made a series of blunders on her Circus world tour.
The 27-year-old singer had accidentally exposed her private parts at one of her gigs, reports The Sun.
However, her "Christmas in March" has beaten all her other faux pas.
Britney was deep into a performance of 'Do Somethin' when she shouted out the seasonal greeting.
