Now that her parents are grooming her to be a bona fide "star", ya'd think Katie would let her stop and sign some autographs!

Katie and Suri smiled but didn't stop as they walked from the theater to their waiting SUV after Katie's performance in All My Sons last night.

Although it looks as if there was one person who was only too happy to stop and sign posters for the fans:
Katie Holmes John Lithgow! But we're betting John was a bit of a let down for the fans. Poor guy, must be tough being outshined by a two-year-old!
