Portia De Rossi reportedly wants to have a baby.

The 41-year-old actress had initially ruled out having children with her wife Ellen Degeneres, 56, whom she married in 2008, but it seems she's now changed her mind and is keen to start a family with her beau.

A source told InTouch magazine: ''All Portia can talk about is beginning a new chapter in their lives and starting a family.''

The couple have allegedly consulted the Center for Surrogate Parenting in Encino, California, to discuss their options, according to the magazine.

Meanwhile, the duo's relationship allegedly hit the rocks recently after an argument reportedly led to Portia seeking treatment in rehab in May for drug and alcohol problems, but they're keen to work through their issues.

A source said previously: ''They've worked out difficulties in the past, and no doubt they're trying to work out any problems right now.''

However, friends of the pair believe they will have patched up their differences by next month and will celebrate six years of marriage by renewing their vows.

The source said: ''They both love to celebrate special occasions and holidays, and their wedding anniversary is no different. They usually celebrate with a big party and invite a lot of friends. They really are a lovely couple. They enjoy being married, and it shows.''
