Lady Gaga has issued an apology after she used the word "retarded" in a recent interview.

The singer used the word when describing comparisons between her hit 'Born This Way' and Madonna's 'Express Yourself'.

The charity Mencap, which specialises in learning difficulties, had condemned the star's choice of words.

In a statement to gossip blogger Perez Hilton, Lady Gaga said: "I consider it part of my life's work and music to push the boundaries of love and acceptance.

"My apologies for not speaking thoughtfully. To anyone that was hurt, please know that it was furiously unintentional.

"An honest mistake, requires honesty to make. Whether life's disabilities, left you outcast bullied or teased, rejoice and love yourself today."
