Reese WitherspoonReese WitherspoonImagine the Avon lady coming to call...

And opening the door to Reese Witherspoon.

It could happen, possibly maybe, as the Oscar-winning actress has signed up to become the face of the cosmetics brand.

Reese yesterday became the beauty company's first ever Global Ambassador.

She will also become honorary chairwoman to Avon's Foundation charity, which supports sufferers of breast cancer and domestic violence.

Speaking at the launch of her new role, Reese told how she was "very excited" to be linked with Avon and proud to be part of the "great philanthropic work" they were doing.

She also said: "I feel a great responsibility in my own life to give back to society."

And added how she was impressed by Avon's ability "to affect real change in the communities in which it does business".
