Kristen Bell goes crazy over sloth [Video]

If Kristen Bell wasn’t a celebrity, people around the world would think she was the sloth version of a crazy cat lady.

The Los Angeles Times reported the Forgetting Sarah Marshall actress had a complete meltdown when she was told she would be meeting her favorite animal on earth, the slow-moving, long-armed sloth.

For her 31st birthday (July 18), fiancé Dax Shepard said he would give his better half “something no one else will ever get in their lifetime."

Unfortunately, he also recorded that moment and now it’s one of the funniest birthday videos you’ll ever watch.

According to the New York Daily News, talk show host Ellen DeGeneres obtained a copy of that video, which features a hysterical Bell right before she meets her first sloth.

"I immediately was overcome and I thought, 'There's a sloth near ... it's close, it's gonna happen.' And I didn't know how to process that, because my entire life had been waiting for this moment," she told DeGeneres Tuesday.

Adding that, "If I'm not between a 3 and a 7 on the emotional scale, I'm crying...I start to have a full-fledged panic attack."

And cry and cry and cry she did. Check out the hilariously adorable video for yourself below.
