Does anyone have recent information on Kim Clijsters and/or Justine Henin?

Clijsters is retired obviously, don't rly know much about her. However i heared of remour about Henin. Apparently she may be coming back. Some people reckon she retired so she could take some illegal medication to help her overcome her injury quicker, so this way the Atp drug test people wouldn't bother testing her meaning she could get away with it. This is a rumour, however it sounds kinda logical because if you were number 1 in the world, why would you just quit tennis?
