A spokesperson for Mischa Barton has brushed off speculation she is engaged to wed after she was snapped with a new piece of jewelry on her ring finger.
The former The O.C. star was photographed attending California's Coachella music festival over the weekend (19-21Apr13) with her boyfriend, British actor Sebastian Knapp, and what appeared to be a gold engagement ring on her left hand.
However, the actress' representative has played down the rumors, telling Eonline.com, "She is definitely not engaged. The ring was just for costume and flair."
It's the second time in recent months that Barton has found herself at the center of engagement gossip - she had to dismiss reports she and Knapp were set to wed in October (12) after she was spotted with a new sparkler on her ring finger. The band proved to be a cheap prop she had been wearing in her stage role as Shelby in a production of Steel Magnolias in Ireland.
