The 31-year-old singer, who has been married before, is the mother of two sons Preston, 8, and Jayden, 7, reported E! online.
"I would like to have more kids, settle down ... Have kids - maybe twins - and get married," Spears said.
The singer, who is currently dating David Lucado, prefers to keep a low-key lifestyle.
"I really don't go clubbing, I don't do that. I like to stay at home, I like watching movies and eating lots of popcorn," she added.
