Though she's a new aunt, Heidi told Us Weekly in March that she and her husband plan to hold off a bit for kids.

"I was like, 'I think I can put this off for a little bit because you look really uncomfortable,'" she joked, referring to her sister's pregnancy. "I was like, 'I’m three years younger. Maybe I can wait three more years to catch up.'"
