"Nothing has been finalized yet," Shuter, who was asked when and how Simpson would adopt, told the Associated Press on Tuesday. He added, "It is true that she's exploring options."
The 25-year-old singer-actress, who filed for divorce from Nick Lachey last December, recently told TV's Extra: "I want to adopt, and I plan to adopt before I have my own kids.
She also said of a particularly well-known adoptive mother, "I think Angelina Jolie has done amazing, amazing things, and the international adoption rate just since her has skyrocketed. It's unbelievable."
