Laura Bush to guest host TODAY

For the first time in history, the first lady of the United States will guest host America's favorite morning program.

Laura Bush will join America's first family for the 9 a.m. hour of TODAY on Tuesday, April 22.

She will also be joined by her daughter Jenna earlier in the broadcast for a special look at their new children's book, "Read All About It!" (published by HarperCollins). Jenna and her sister Barbara will also discuss what it's like to grow up as a twin.

During her day as a TODAY guest host, Mrs. Bush will learn the ins and outs of hosting a morning show, and she will participate in several segments and interviews.

In addition to her hosting duties, Bush will also give Ann Curry a rare look inside the Bush family ranch in Crawford, Texas.

She will give Curry a tour of the ranch, and explain the "green" eco-friendly design of the home.

Laura Bush has always been passionate about reading. An honorary ambassador for the U.N. Literary Decade, she hosted the first-ever White House Conference on Global Literacy in 2006, which ignited international cooperation to build free societies through literacy.

In 2001 she joined with the Library of Congress to launch the first National Book Festival in Washington, D.C.

As first lady of Texas, Bush founded the statewide Texas Book Festival in 1995. She taught in Dallas, Houston, and Austin public schools.

"Read All About It!" is her first book.
