Pregnant Kourtney Kardashian revealed the identity of her baby's father on the Today show this morning: Scott Disick.
The E! reality star and Disick split in February, but recently reunited, Kourtney said.
"He's very excited. When I found out, I was so shocked. I didn't know what to do. He was so for it and so excited from the beginning. And we're really happy," Kourtney added.
When asked about marriage, Kourtney – who is due in December – said, "We'll see."
Kim tells Usmagazine.com she can't wait to be an aunt.
"It's the first addition to the Kardashian clan, and we only wish that our dad could be here and experience this with us," Kim went on. Her father, Robert Kardashian, a prominent lawyer who defended O.J. Simpson, died of esophageal cancer in September 2003. (Mom Kris split from him in 1989, and wed Bruce Jenner in 1991.)
"Everything like this, huge things that happen in our life, is a little bit bittersweet, but we're all so excited," Kim added.
Kourtney's new reality show, Kourtney and Khloe Take Miami, premieres Sunday.
