Katie Holmes stepped out of a chauffeured SUV in NYC today, smiling and chatting on her cell phone. Katie was solo as she headed back to her apartment, but she's been spending a lot of time out and about in the city with Suri lately as Tom Cruise gears up for his next role in New Orleans. Katie's mother, Kathleen, even paid the girls a visit to make the most of their girls-only time. Katie was also seen enjoying some alone time last week as she headed to a performance of Evita on Broadway. She hasn't appeared on the big screen since her turn in last Summer's Jack & Jill, but she's been keeping busy with her other duties, including her role as designer for her joint line with Jeanne Yang, her stylist. The duo was recently featured in a special issue of The Hollywood Reporter dedicated to Hollywood's top star and stylist pairs.
