<P>Madonna's Blond Ambition tour corset is set to be auctioned in London.</P>
The Queen of Pop's outfit by Jean-Paul Gaultier - which is green silk with conical cups and beaded fringe and which she wore on the 1990 tour - is expected to sell for at least 10,000 pounds, Christie's estimated.
Another item going under the hammer is a watch which was one of Elvis Presley's last Christmas presents.
The watch, estimated to sell for 6,000 pounds or more, is a diamond-set Rolex given to Elvis by his longtime manager Tom Parker. It is engraved, 'Elvis Merry Christmas your pal Col. Tom Parker.' It was the last Christmas for the star, who died the following year.
Christie's previewed the sale on Friday. The auction will be on Thursday.
