Perhaps planning her own Broadway appearance, Jessica Biel is catching up on her shows. The actress, who wed Justin Timberlake in October, was spotted at “The Book of Mormon” Tuesday, and later tweeted a rave review — “Book of Mormon was too good for words . . . Except for words like amazing and best musical I’ve seen in forever and incredible!” Wednesday, Biel took in “Cat on a Hot Tin Roof,” which stars Scarlett Johansson, Ciarán Hinds, Benjamin Walker and Debra Monk.
