Keeping up with Khloe Kardashian will soon be easier: the star, 26, and her hubby, L.A. Laker Lamar Odom, 31, are set to premiere their new E! reality series, Khloe & Lamar, this Sunday.

When Us Weekly first broke the news of the duo's spinoff in December, a source said the series will have the vibe of Bravo's Bethenny Getting Married: "They're so cute, playing off one another."

Topics of discussion on the show's premiere? Love, basketball, and, of course, hopefully becoming parents.

"I think Lamar and I would be such great parents," says Kardashian of her hubby, whom she wed in September 2009 after just 32 days of courtship.

And although marriage came quickly for the pair, starting a family, on the other hand, hasn't been as easy.

"If it happens, it happens," Kardashian tells "It takes time, I guess."

Not that Kardashian and Odom, 31, haven't been actively trying to conceive a child.

"I don't know what the problem is," Kardashian tells Us.

Check out the above sneak preview of Khloe & Lamar and tune into the full episode Sunday at 10 p.m. (EST) on E!
