A pair of earrings Whitney Houston wore in 'The Bodyguard' are to be sold in an auction of her possessions.

The jewellery - which the late star donned opposite Kevin Costner in the hit 1992 film - is among several items that once belonged to the singer which are to be sold by Julien's Auctions in Beverly Hills as part of their 'Hollywood Legends' sale.

Other items include a black velvet dress owned by the 'I Will Always Love You' singer and 15 other outfits worn by the pop legend.

Julien's Auctions owner Darren Julien has revealed over 50 friends, family and former colleagues have contacted his office offering to sell items since her tragic death at the age of just 48 in February.

He said: ''This is something that commonly happens after somebody passes ... especially someone with the status of Whitney Houston. Her items can increase 10, 20 even 30 times compared to their previous value prior to her death. These items become part of history really.

''Whitney is a legend so it's definitely an appropriate auction for her. It's a reason to celebrate her life, not put these items in a box under the bed ... Her items are now more sought after.''

Darren believes bids for Whitney's dresses will reach tens of thousands of dollars because she is someone ''that will maintain a collectability'' because of her incredible career.

The 'Hollywood Legends' auction will also include pieces that once belonged to Princess Diana, Charlie Chaplin and Charlton Heston and will take place on March 31 and April 1 at Julien's Auctions in Beverly Hills, California.

Whitney herself was an avid collector of Hollywood memorabilia and one of her most prize possessions was a pair of Ginger Rogers' dancing shoes which had been personally signed by the screen icon.

The shoes were given to her as a gift by David Gest for performing at the 10th Annual American Cinema Awards in 1993 on the night where Rogers was honoured for Distinguished Achievement In Film.

Ginger personally signed each shoe with a note which read ''to one of the greatest singers of all time, from your friend Ginger Rogers''.

David - who was invited to the 'My Love is Your Love' singer's funeral - believes the unique item would fetch thousands of dollars if Whitney's 18-year-old daughter Bobbi Kristina - her child with ex-husband Bobby Brown - decided to sell the shoes.
