Bride-to-be JENNA BUSH revealed some more tidbits to ET about her upcoming May 10th wedding to fiancé HENRY HAGER. The first daughter is expected to tie the knot in an outdoor ceremony at her father's ranch in Crawford, TX.

Jenna appeared at the 92nd Street Y in New York with her mother, LAURA, to talk about their new children's book, Read All About It!, which encourages children to embrace the delights of reading. A portion of the proceeds from Read All About It! will benefit two national teacher programs: Teach for America and the New Teacher Project.
