Watch: Nicole Richie gets marshmallows shoved in her mouth for Ellen challenge

Nicole Richie's got one big mouth.

The blue-haired beauty stopped by The Ellen DeGeneres Show earlier today, to help break the talk show host's marshmallow-eating record… by shoving as many of the sweet treats in her trap as possible.

The best part? She can't use her own hands. Get imaginative FIXers… and watch the video above.

Despite ending up with post-marshmallow powder on her face, at least the 33-year-old got her own candy crown and tacky teal sash… along with the sugar high.

This comes just days after the reality star visited Extra! TV, to talk about season two of Candidly Nicole.

Which doesn’t see her chowing down on confectionary, but does see her dabbling in magic. Check that out below!
