"Nothing has been finalized yet" as to when and how Simpson will adopt, her publicist, Rob Shuter, told The Associated Press on Tuesday. But he added, "It is true that she's exploring options."
Shuter said Simpson and her family have anonymously contributed funds to a smattering of Mexican orphanages for several years now. The singer started visiting the orphanages with a church group at age 11.
"I want to adopt, and I plan to adopt before I have my own kids," the pop star recently told TV's "Extra."
In the interview, Simpson cited a certain high profile mother as an influence.
"I think Angelina Jolie has done amazing, amazing things, and the international adoption rate just since her has skyrocketed," she said. "It's unbelievable."
Simpson is best known for starring in the MTV reality show "Newlyweds: Nick & Jessica" with Lachey, who gained fame as a member of the boy band 98 Degrees.
