U.K. Singles Chart: Britney Spears Tanks With 'Femme Fatale'

Let's forget the fact the Jennifer Lopez's "On The Floor" has debuted at #1 in the UK, thus giving the American Idol judge her first chart-topper across the pond in six years—because Britney Spears' Femme Fatale has completely flopped in its first week on the chart in Old Blighty.

Wigney's seventh studio album bombed its way in #8 in the UK. Even Christina Aguilera's massive flopzilla of an album Bionic debuted at #1 there last year. And it's really not that surprising, given that Femme Fatale's lead singles "Hold It Against Me" and "Till The World Ends" charted at a disappointing #6 and #21, respectively.

Meanwhile, Adele has racked up a 10th week at the top of the chart in her home country with 21, giving her the longest stretch at #1 in the UK since Dire Straits achieved the same feat in 1986 with Brothers In Arms.

Oh, well. At least Britney can be happy that her album is #1 in Australia—a first for her.
