— -- Kristen Bell accidentally grabbed an Uber that was a carpool option on Thursday. That's when the "Frozen" actress decided to live tweet the entire experience.

"Didn't know @uber had a carpool option, but my driver just pulled over and said "gotta pick someone else up". this should be fun," she wrote. "Come to think of it, i did press "pool" but i thought it was a fun summer reference. like how @google changes fonts to celebrate holidays."

Then Bell, 34, wrote on Twitter: "if I'm not home in 10 minutes pls call the police and tell them i was last seen in a honda accord with 2 males mutes. #ubercarpool."

Then panic set in!

"Not sure where the other rider is headed but were getting close to my house. then it occurs to me "WHAT IF HES COMING OVER?" #ubercarpool," she wrote.

But everything worked out in the end.
