Portia de Rossi has officially taken wife Ellen Degeneres' last name. A Los Angeles Superior Court commissioner granted De Rossi's request to take the last name of her partner during a closed hearing Thursday. The television star will now legally be known as Portia Lee James DeGeneres. The couple was married in August 2008. The 37-year-old Australian-born actress asked for the name change last month. Neither woman attended the hearing. They married during the five-month window in which gay marriage was legal in California. Portia DeGeneres is well-known for her roles on several television series, including 'Ally McBeal,' 'Arrested Development' and 'Better Off Ted.'
