Hollywood actress Kristen Bell loves sloths. It can be said that is she is even obsessed with them. She curled into a ball and broke down in tears when she learned she was going to see a sloth for her 31st birthday. A funny video from the moment she found out about the gift shows her crying on her bed and having what she described as "a full-fledged panic attack."

The "Forgetting Sarah Marshall" star told Ellen DeGeneres on the show about the experience which was a surprise birthday present from her boyfriend, "Parenthood" actor Dax Shepard. When Shepard told her he had planned a surprise, Bell said she knew that it would involve a sloth.

"I didn't know how to process that. My entire life has been waiting for this moment, where I would get to interact with a sloth," she said on Ellen. "Knowing that a sloth is here, I start to have a full-fledged panic attack. I don't know how to compete with all of this emotion, I'm crying so hard," the actress further shared.

Shepard begins filming as he walks into the bedroom and finds Bell crying on the bed.

"You're supposed to see the sloth and I'm supposed to film it," he can be heard telling her in the video. When Shepard asks why she is crying,

"I'm so excited!" Bell replied. The actress gets even more worked up upon hearing that the furry creature may be hanging around for the day. She sits straight up and asks "He's coming to the party?" like a five-year old kid.

The sloth named "Melon" was a guest at Bell's birthday bash later that day. The animal played on a makeshift jungle gym for three hours while guests partied.
