Lady GaGa is parting ways with her red Rolls-Royce Corniche Iii convertible to benefit the MusiCares charity.

The luxury vehicle, in which she travelled to Manhattan's Guggenheim Museum for an event in September, 2012, is to be auctioned off at the upcoming Julien's Auctions Music Icons, Legends and Rebels sale in New York.

The car is expected to fetch between $30,000 (Gbp19,000) and $50,000 (Gbp31,250) when it goes under the hammer on 17 May (14) at the Hard Rock Cafe auction, where one of Gaga's Philip Treacy hats and a stage worn headpiece are also among the lots.

The auction highlights also include George Harrison's 1962 Rickenbacker guitar, a Paul MCCartney-used Hofner Bass guitar, Elvis Presley's onstage jumpsuit, U2's With Or Without You MTV Award and Michael Jackson's handwritten lyrics to Billie Jean.
