Katie Holmes and Suri Cruise
Holmes went from teen television sweetheart as Joey on the '90s primetime soap "Dawson Creek" to sharply coiffed A-lister when she began dating and eventually married Hollywood veteran Tom Cruise. The actress now boasts a fashion line in addition to her outsize celebrity status.
Suri Cruise just turned 6, but she has been a pop culture fixture for years. Tabloid interest in her birth reached a fever pitch, she's the subject of a widely read blog which has reportedly just scored the author a book deal, and she has been named the influential celebrity child in the world.
