Sugababes dropped from US label?

Sugababes are rumoured to have been dropped from their US label.

The band, who signed a three-album deal with Jay-Z's Roc Nation in April 2009, released their new record Sweet 7 last week, where it charted at a disappointing number 14 in the UK.

According to Ace Showbiz, the group's name has now been removed from the label's website.

Sweet 7 was released after a series of delays, following former band member Keisha Buchanan's ousting in September last year.
