Model Rob Kardashian is happy with sister Kim's pregnancy news, but says he wants to get "married first" before he starts a family.
"I am so proud of my sisters, but I'll be married before I have a baby," people.com quoted Rob as saying.
Kim, 32, is currently dating rapper Kanye West, while Kourtney, who is mom to Mason, 3, and Penelope, 6 months, is not married to her children's father, Scott Disick.
When asked about an impending proposal from Kanye West to Kim, he said: "I think everyone is just excited about and focused on the baby right now. Kim and Kanye are over the moon happy. I am so excited to be an uncle again."
