Happy Sesame Street Day!

Remember when you used to watch Sesame Street? You can totally admit it- We all did!

Well in honor of Elmo and of course Mr. Grouch, we use this day to celebrate the 45th anniversary of the first broadcast of Sesame Street!

Elmo, Big Bird, and Cookie Monster have definitely had their fair share of Celebrity guests these past 45 years. Celebs like Kristen Bell, David Beckham, Sofia Vergara, and Alec Baldwin all guest starred on the show, even including Mr. Bill Cosby. I think it’s safe to say Sesame Street has a place in your heart no matter how old you get!

To celebrate a special day in honor of our childhood, we’ve decided to look back at some of Hollywood’s stars on Sesame Street.
