Grey's Stars in Baby Battle

Wondering why Ellen Pompeo didn’t announce the arrival of her daughter—who was born last Tuesday—until yesterday? Perhaps it’s because her Grey’s Anatomy co-star Katherine Heigl chose last Tuesday to make the adoption of her own daughter public. "It was very curious timing,” a source tells the New York Post. "It was an adopted kid—she could have chosen any other day to make it public.”

Pompeo then, conveniently enough, chose yesterday—the day Heigl and her daughter appeared on the cover of People—to make her announcement. “It looks like they were trying to one-up one another,” says the source.
