Britney Spears' changed the name of her controversial new single from her latest Circus after US radio stations threatened to ban it.

Her third single, If U Seek Amy, does not have a swear word, but the inherent sexual innuendo has been deemed inappropriate for Spears’ young fans.

But all of the boys and all of the girls are begging to if you seek Amy, is the song's phrase that is also causing unrest among radio stations.

In a bid to avoid backlash during her comeback and world tour, Spears has changed the title to If You See Amy.
