Lady Gaga's piano fails to sell

The 'Poker Face' hitmaker's old instrument, which she used to write her first song on at the age of just five, was expected to sell for $100,000-$200,000 when it went under the hammer at the Hard Rock Cafe New York on Saturday, as part of Los Angeles-based auctioneers Julien's Auction's Music Icons memorabilia sale.

However, it failed to meet the reserve price - the lowest amount a seller will accept for their lot - and didn't sell, though a spokesperson for the auction house wouldn't reveal the minimum it could have changed hands for.

It is not yet clear whether the instrument will sell.

While Gaga's piano wasn't a hit at the auction, over 85 items which had previously belonged to Elvis Presley proved popular, with a 1969 Gibson Dove guitar that the late singer' father made for him fetching a huge $334,000.

The 30-year-old singer - whose real name is Stefani Germanotta - previously spoke of how she began learning to play the piano when she was just four years old and her parents taught her to be disciplined by insisting she attended the lessons they organised, as well as practicing regularly.

Discussing how she felt "isolated" and "lonely" as a child, she said: "I did feel very isolated as a young person, and not because I was alone or abandoned by my family, it's just a chemical thing. Some kids are born like that. We don't know why we feel lonely, but we do. It's like depression but it's not because someone neglected me. I grew up in a very disciplined household. I played piano when I was four. I sat at it and I started to play it. Did my parents then say to me that we are giving you lessons? Yes. And then when I tried to stop playing they said, 'You can sit there for an hour and practise, or you can sit there for two and not practise.' "
