Rumors that Ellen DeGeneres and Portia de Rossi are headed for divorce have been circulating for several weeks now.
Portia completed a rehab stint back in May, and sources close to the couple have claimed that she sought treatment after being issued an ultimatum by Ellen.
De Rossi reportedly displayed violent tendencies while drunk, and after numerous fights (which Portia may have videotaped), Ellen reportedly got fed up and demanded that Portia quit drinking.
Now, it seems that Ellen's behavior may have actually triggered Portia's excessive boozing.
A friend of the couple's tells In Touch that Ellen "had an affair with one of their mutual friends right before Ellen's rehab stint in May." The insider adds that Ellen's infidelity prompted Portia to embark on a disastrous bender.
