Smitten kitten! Khloe Kardashian is making long-term plans with French Montana; in fact, the reality TV star wants to have his baby, a source exclusively tells Us Weekly.

"Khloe's smitten," the insider tells Us, "and her goal is to get pregnant—soon!"

Indeed, the reality TV star, 30, gushed to Us last Friday, July 4, that she's enjoying her dynamic with the "Cocaine Mafia" rapper, 29. "It's fun," Kardashian told Us at her Tao Las Vegas 30th birthday bash. "I like how he's always happy. Smiles are infectious. They're contagious. I like that." Added the star: "French is just what I need right now."

As "light and easy!" as the relationship has been, Kardashian is ready to be a mother. "She stayed with Lamar Odom through everything because she was dying for a baby," the source explains of the aunt to Mason, 4, and Penelope Disick, 2, and North West, 12 months. "And she still is."

While the star and her rapper beau have no engagement plans yet, the insider adds that "she says she could see herself with French in the long run." For now, though, it appears that the two are (ahem!) spending a lot of quality time together.

"It's a very sexual relationship," adds another confidant of their six-month romance. "Khloe likes bad boys, and she wants to reform French."

The two have raised eyebrows in recent months, especially after posting questionable pictures to their social media accounts. Their latest updates include a racy picture posted by Montana on Thursday, July 10, of his lady's famous butt.
