Wedding bells, here we come?

Mischa Barton sparked engagement rumors when she was spotted at Coachella over the weekend wearing a sparkly ring on her ring finger.

So is the former The OC star engaged to boyfriend Sebastian Knapp? 

Not so, says E! Online.

"She is definitely not engaged," claims Mischa's rep. "The ring was just for costume and flair."

We're a bit bummed to hear that they're not actaully engaged, but we're glad that the 27-year-old actress seems to be in a happy relationship at the moment.

Now we're just hoping to see Mischa in a TV  show again before too much longer - preferably one that is at least close to as good as The OC was.
