Portia de Rossi was supportive of wife Ellen DeGeneres' switch to a vegan diet but, according to reports, now feels the animal-free lifestyle is aging her.
"Portia was totally on board when Ellen eliminated all refined sugars from her diet and went back to becoming a vegan," a source said. "But now she feels Ellen's looking gaunt and unhealthy -- and has simply gone too far!"
Portia, who also follows a vegan diet and has battled with eating disorders, apparently feels Ellen has become too thin.
"Ellen's dropped about 10 pounds and Portia keeps telling her that being too thin is making her look older than she really is," the source added. "Ellen snaps right back at her, saying she likes looking thin -- and to butt out!"
