Lady GaGa has singled out 'Bad Romance' as her favourite song she has written.

The singer claims the 2009 single - which reached number one in the UK singles chart and number two US - is "special" to her because of how it was received by her fans, who she calls 'Little Monsters'.

When asked which of her tracks she likes best, she replied: "Well, it's so very difficult to say. I love all my songs so much.

"Well, 'Bad Romance' has a special place in my heart because it meant a lot to the Little Monsters when it came out."

The 25-year-old star also has a great affection for 'You and I' and chooses 'Poker Face' as her third favourite song, and also admitted she has "artistic rebirths" where she imagines her tunes in different styles.

She added to popdust.com: "I also think 'You and I' is one of the best songs I've ever written. But the third best song. Well, I suppose I would have to say 'Poker Face'.

"But see, I have very different feelings about different songs at different times. I could also say that 'Fooled Me Again' is one of the best songs I've written, and that was never on any of my albums. I could say that 'Marry the Night' is my third best song, or 'Americano'.

"I go through these artistic rebirths where I envision my songs in completely different ways. But I guess I'd say my third best song is 'Poker Face'."
