What do Dakota Fanning, Jodie Foster, Ron Howard, Fred Savage and the Olsen Twins all have in common? Liliana Mumy, their costar on A&E Biography's "Child Stars II: Growing Up Hollywood," and the girl everyone in Tinsel Town is talking about. OK, maybe not everyone. Maybe just me and the producers of Cheaper by the Dozen 3. That's right, she's "that kid" -- better known as Jessica Baker of the famous Baker clan. You know, the redhead girl twin with the freckles. She's the one who tells Mark, "Your eccentricities and vision problems could be linked to any number of the Baker ancestors."

Born to actor Billy and his birthing coach wife in 1994, Liliana Mumy (pronounced "moomy," not "mummy") has had a landmark career. In addition to having three dogs (Hurley, Bucky and Minnie), her accomplishments include a 20-second appearance on Scrubs, guest spots on That '70s Show, Strong Medicine and The Twilight Zone, and a recurring role on My Wife and Kids. But that's not all. Liliana, who, coincidentally, is sister to Seth (you know, that kid from Paulie) has appeared in movies ranging from The Santa Clause 2 in 2002 to Stitch! The Movie in 2003.

So you see, Liliana Mumy was not just pulled off the street to costar in 2003's Dozen or in 2005's Dozen 2. She is an actress. She's done it, kids, she's really done it. She's achieved everything that a little girl could ask for. Fame, fortune and a role in this year's The Santa Clause 3. Big things are happening for Liliana Mumy. And now whenever you see her you can put a name to that adorable freckled face.
