Jennifer Aniston has been researching adoption after her close friend Sheryl Crow opened her home to a second child.

Earlier this month, the singer revealed she had adopted a son, Levi James, who was born on April 30. Sheryl also has three-year-old Wyatt, who she adopted in 2007.

"Jen has seen how happy Wyatt, and now Levi, make Sheryl," a source told the NationalEnquirer magazine. "And Sheryl has told Jen, Don`t wait fora man to make a family!`"

Jennifer is believed to have been in contact with her lawyers to discuss adoption and she is hoping tomove forward with her plans soon.

"Money isn`t an issue, but time is," the source explained. "Jen doesn`t want to wait four years, like Sandra Bullock did, to get her adopted child. She`s hoping it will take no more than a year."

Sheryl has invited Jennifer to visit her sons and spend time with them.

The 48-year-old music star has previously revealed she has discussed adoption with Jennifer, telling her famous friend it was the best thing she has ever done.

"We`ve talked aboutit," Sheryl said in 2008. "For me, it has been the most incredible experience. I never knew how much love I would give and feel."
