Kim Kardashian has reportedly been talking about starting a family with beau Kanye West sooner rather than later.

The reality star has just become an aunt for the second time following the birth of Kourtney's daughter Penelope.

And RadarOnline claims that Kim is excited to become a mother herself in the near future because she believes she's found "the one" in the rapper.

"Kim gushes about how happy she is with Kanye all the time and she is already talking babies with him too," a friend told the site.

"She is really head over heels for him and she's always wanted to be a mom and Kim is really hopeful that Kanye will be the guy she finally has a family with.

"They've both talked about how they would love to have children, and about how they both think the other would make a perfect parent.

"She won't get pregnant before her divorce is finalised but I wouldn't be surprised if they start trying for a family the second the ink is dry on her divorce papers."

Kim's divorce battle with estranged husband Kris Humphries is still ongoing following their ill-fated 72-day marriage.
