There's something about Betty.

PBS has an upcoming special that centers on the legendary comedian. Called "Betty White: First Lady of Television," it will look at 80-year career of the prolific actress. The network released a clip late last week, and it features interviews with White herself, along with A-listers like Ryan Reynolds and Tina Fey, among others.

The new PBS clip focuses specifically on a more recent milestone for White: the first time she hosted "Saturday Night Live." We get an look at what it was like for her, and you may be surprised to learn that she had a serious case of stage fright before the live show. Even pros get nervous before a huge performance like that.

Watch the clip below.

Some of the other stars who provide insight are Valerie Bertinelli, Georgia Engel, Valerie Harper, Jennifer Love Hewitt, Gavin MacLeod, Carl Reiner, Tom Sullivan, and Alex Trebek.

"Betty White: First Lady of Television" is almost here. The special airs Tuesday, Aug. 21 on PBS. Be sure to check your local listings.
