Reality TV star Kourtney recently revealed she is expecting her second child with boyfriend Scott Disick. Her delivery is due in May next year.
Kendall wants the couple to have a baby girl because she thinks their first child, two-year-old son Mason, would be a protective big brother.
"I want (Kourtney) to have a girl. It would be so cute because when they're older, Mason could be like the protective big brother. And I feel like Kourtney could have fun with a girl-dress her up in little tutus and everything," contactmusic.com quoted the 16-year-old as saying.
