"Portia De Rossi secretly spent 30 days in rehab" says reports.
The 41-year-old actress reportedly sought treatment at Passages Malibu rehab facility for drug and alcohol issues after an argument with her wife Ellen DeGeneres.
A source told In Touch magazine: "They got into an ugly fight. Portia hadn't been happy for a while and was drinking and isolating [herself], and Ellen confronted her”.
"Portia lost it and blamed Ellen for driving her to drink because of her controlling ways and said she wasn't in love with her anymore. Ellen was crushed and screamed at Portia to get out."
The chat show host, 56, who married Portia in 2008, reportedly visited the blonde beauty at the facility every weekend to provide support during her alleged treatment.
The pair, who were spotted out in New York together in mid-June, are now determined to make their relationship work following the alleged stint in rehab.
The insider explained: "They are on their way to repairing their marriage. It won't be easy. Portia will always be battling these demons. But they love each other."
Meanwhile, this isn'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 16kg.
