Katie Holmes debuted a sleek and shiny head of hair leaving an appointment and heading to a studio in LA yesterday. On Tuesday, she made a fashionable appearance on behalf of Ann Taylor at a catered lunch thrown in the penthouse of the Chateau Marmont. She's the face of their Spring ad campaign and showed up in a bright, colorful, red skirt for the party. It's been a busy month for Katie, Tom Cruise, and their daughter Suri who marked her 5th birthday with friends and family at a luxurious outdoor soiree. Katie has another reason to celebrate after settling her lawsuit against Star magazine for their false claims of drug use. Tom's also in high spirits as Top Gun turns 25 and is honored with special screenings at AMC Theaters nationwide.
