Anderson Cooper: 'I've Always Giggled Like a Teen Girl'

Anderson Cooper carries a backpack while walking down the street on Tuesday (August 23) in New York City.

The 44-year-old CNN anchor has spoken out about his now infamous on-air laughing fit.

“I don’t know what happened with the giggling. I mean, I’ve always giggled like a 13-year-old girl at a Justin Bieber meet and greet. There’s nothing I can do about it but I’ve never not been able to stop,” he told EW.

“I’m a little stunned by how many people have seen that video. I went to bed telling myself, ‘I doubt anyone will notice the giggle fit.’ I woke up and in the elevator the first thing my building super said to me was, ‘What’s wrong with your laugh?’” he added.
