Liv Tyler has left question marks hanging over her marriage to British rocker Royston Langdon, after posing at New York's Costume Institute Gala on Monday night without a wedding ring. The couple married in March 2003, and have a three-year-old son, Milo.

However, sources claim the relationship has been on the rocks for some time; rumors seemingly confirmed when Tyler strolled the red carpet alone at the star-studded event, with a clearly naked ring finger - the same night Scarlett Johansson was showing off her brand new engagement ring.

When contacted by the New York Daily News, a representative for Tyler, 30, refused to comment on the speculation surrounding her marriage.
