Sesame Street, the beloved children’s television show, is celebrating the air of 40 years of success. Apparently, there are going to be tons of celebrities as special guest stars this season, and Sarah is one of them! Check it out:

“Sesame Street,” the beloved children’s show, turns 40 this week. The longest-running show in children’s television history, whose fuzzy, lovable muppets are now seen in more than 140 countries, revolutionizing children’s television. “Sesame Street” became the first show for kids that had education as its guiding principle and used the power of TV to teach.

Today is the season 40 premiere, but Google.com celebrated early, including Big Bird’s feet in the “Google Doodle,” the icon on the site’s homepage. Bert and Ernie, Cookie Monster and Count Dracula also graced the site.

And the show is pulling out all the stops, planning a season filled with celebrity appearances, by Cameron Diaz, Sarah Jessica Parker, Kobe Bryant and others. First lady Michelle Obama will plant a garden with Big Bird and Elmo, pushing a new focus on nature, the environment and “green” issues.
