Ellen DeGeneres is reportedly giving up alcohol

A source told US OK! magazine: "Ellen has always been a big drinker.

"She loves her wine but she's realised her behaviour has only enabled Portia to drink as well, and she feels partially responsible for Portia's rehab stint."

Ellen, 56, who married the actress in 2008, is determined to do anything to make sure Portia, 41, remains healthy following the successful 30-day stint at Passages Malibu rehab facility.

The source explained: "Ellen loves Portia more than anything in the world and wants to make sure she's healthy, emotionally and physically. She's realised that drinking in front of Portia is just selfish. Right now their marriage is better than it's been in years, and Ellen is just grateful that her wife is healthy again. She's ready to enjoy every minute that she has with Portia."

Meanwhile, this wasn't the first time Portia has been admitted to a rehabilitation centre as she also sought treatment for an eating disorder in 2000 after her weight reportedly plunged to just 82lbs.
