The 'Love on Top' superstar, who welcomed daughter Blue Ivy in January, suggested that she may bring up more than two children.
"I definitely want to have more," Beyoncé told ET Online. "I don't know how many. God knows I don't know yet."
She added: "I have such a full life. I feel like now I know the reason that I was born."
The 30-year-old, who married Jay-Z in April 2008, has previously said that the birth of Blue Ivy has made her "feel powerful".
