The actress revealed she knows when the question is coming when she is asked, "something about family and trying to relate it to a movie with, 'Oh, if I was to have a child how many kids do I want?'
"And, 'do I want a boy or a girl?'," Jennifer, 44, revealed in an interview with ABC News correspondent Amy Robach.
"I didn't realise you could place order," she quipped. "I honestly didn't realise it was like a drive-through, that you could talk to a little electronic voice."
The star, who is happily engaged to Justin Theroux, added, "My friends and my partner are truly my family."
Jennifer then confirmed that the couple are in no hurry to tie the knot – despite reoccurring rumours of an impending wedding.
"I surround myself with my amazing work, my amazing friends, my amazing partner, my beautiful dogs… and I tune that noise out," she commented.
"I mean I think it's very sweet that people want everything for me," she said of the public interest in her private life, before emphasising that she is "so content and happy".
The actress also discussed how she prepared for her role in We're The Millers, in which she played a stripper.
"I said 'yes' (to the role) thinking 'wouldn't that be great', thinking 'well, I've never played a stripper, at least not in film," she said.
"Then this panic sets in three weeks, two weeks, one week before the actual day of shooting."
The superfit star said she worked out six days a week to hone her body.
"Honestly, it was the craziest workout," Jen admitted. "My diet has always been pretty clean but I think I was super, super strict, especially in terms of, I'll usually cheat one or twice a week and I just kind of didn't."
