Jennifer Aniston Feeling Pressure From Her Family To Get Pregnant?

In a new interview with the UK's Marie Claire magazine, Theroux said last week that he's been thinking more and more about fatherhood these days, especially since her plays one on HBO's The Leftovers.

He said, "The strange thing is that I've started to feel oddly parental towards my on-screen children. They've just moved to New York for the show and I've gotten a little protective, making sure they get home OK. I find myself checking in on them at the weekend - are you doing alright? Did you work that out? Wait, when are you moving? Who's moving you? I'm a real protective fake dad.' Good practice, I venture? 'Well, I'm great with teenagers but the in-between bit... at least I didn't have to deal with any diaper changing."

Meanwhile, there have been reports that have said that Aniston and Theroux are rumored to be adopting a baby.
