BEVERLY HILLS, Calif. -- Reese Witherspoon is now an Avon lady. The Oscar-winning actress has been selected as the company’s first-ever global ambassador.

Witherspoon, 31, will serve as honorary chairman of the Avon Foundation, which focuses on the issues of breast cancer, domestic violence and emergency relief.

She will also be a spokeswoman for Avon Products Inc.’s beauty brands and sales representatives, it was announced Wednesday.

Terms of her multiyear agreement weren’t disclosed.

“I’m very excited about working with the Avon Foundation, with many different aspects of it,” Witherspoon said at a press conference. “First and foremost, breast cancer research and awareness, programs that they’re working on. Someone very close to me is a breast-cancer survivor. It’s a cause that’s very close to my heart.”

Witherspoon won the best-actress Oscar in 2006 for her role as June Carter Cash in “Walk the Line.” Her film credits also include the “Legally Blonde” movies, “Election” and “Sweet Home Alabama.”
