It's splitsville in Sin City.

Hotel heiress Nicky Hilton (search) and New York businessman Todd Andrew Meister (search) have officially ended their brief marriage.

A Las Vegas (search) judge on Tuesday granted the newlyweds an annulment, according to a joint statement issued by the couple's representatives.

"Both parties have ended the marriage amicably, and they remain good friends," the statement said.
