mtv movie awards Paris Hilton Nicky Hilton

They may not be nominated, but the Hilton sisters are never ones to miss out on a killer party!

Looking lovely as ever, Paris sparkled in a sexy sequined charcoal dress with silver embellishment, while sister Nicky opted for a dull grey strapless number that was very much overshadowed by her sister's sparkly gown at the MTV Movie Awards, on Sunday night.

Which Hilton sis looked hotter?
