Betty White takes 'Middle' ground

Veteran actress will guest star on comedy's season finale

The gigs just keep coming for comedy veteran Betty White.

The former "Golden Girl," whose comedy pilot "Hot in Cleveland" was recently picked up by TV Land to series for a summer launch and who was just tapped to host "Saturday Night Live" on May 8, has also been signed to appear in the season finale of ABC's comedy "The Middle."

In the episode, which shoots next week, White will play a school librarian who confronts Brick (Atticus Shaffer) over his failure to return numerous overdue books.

"The Middle," which stars Patricia Heaton as a harried Midwest mom, has been renewed for a second season.
