Nicole Richie Does The Hilarious Chubby Bunny Marshmallow Challenge on ‘The Ellen DeGeneres Show’ [WATCH]

The Ellen DeGeneres Show is wild, crazy and totally entertaining, so when reality star Nicole Richie stopped by hilarity was bound to ensue. Ellen DeGeneres helped Nicole do her own version of "Chubby Bunny" marshmallow challenge on Thursday's episode.

"Chubby Bunny" is a game where you stuff marshmallows in your mouth and say "Chubby Bunny." The person who has the most in their mouth and can still say the words, wins. When Nicole stopped by Ellen's show to promote the second season of her AOL series, which aired as extended versions on VH1 this summer, Candidly Nicole, she was put to the test using lots of marshmallows.

Nicole and Ellen teamed up to try and break the record for most marshmallows stuffed into an Ellen guest's mouth in 45 seconds. The mother of two had a little advice for Ellen before they began the hilarious challenge. "Okay, wait, can I tell you a trick? I think you gotta shove them to the side [of my mouth] so I have some storage," Nicole told Ellen. "You just quiet down," Ellen joked.

After the challenge started, Nicole could not stop laughing and even had tears coming down her face as Ellen stuffed her cheeks full of fluffy marshmallows. Once the challenge was completed, Ellen announced, "You're the official world record holder because no one else has done it!"

Nicole then posed in a marshmallow crown and sash reading, "World Record."

While promoting her second season of Candidly Nicole in another interview today with Ryan Seacrest during his On Air with Ryan Seacrest radio show, Nicole teased her Halloween costume possibilities for this year's holiday.

"I really don't know what I'm going to be. Last year, I was Danny DeVito and I had my friend who's 6'1″ be Arnold Schwarzenegger and we were "twins." So I like to keep that kind of late '80s and early '90s style ... [Joel Madden's] not that enthusiastic about Halloween. I am. I love dressing up. I like to be warm. I don't want to wear booty shorts. That's not me. I like to keep it light-hearted and funny," Nicole told Ryan.

Nicole's AOL series returns tonight on AOL.com. The extended versions will return to VH1 in Spring/Summer 2015.
