Khloe Kardashian is rumored to be expecting her first child with ex-husband Lamar Odom just days after the two announced they had finalized their divorce two years after it as initially filed.

Although now reported to be dating NBA star James Harden, a source tells OK magazine the "Keeping Up with the Kardashians" star has "still been seeing Lamar. The fact is, she would consider being exclusive with James if it weren't for Lamar."

According to the magazine, while she and Harden were recently in Las Vegas, Kardashian snuck off to be with Odom, who has recently been staying there following the recent deaths of two of his close pals. Even while she was rumored to be dating rapper French Montana, Kardashian recently told E! Online, "I will never ever not love Lamar. I'm obsessed with Lamar in a great, healthy way. He was my husband, and I wish he was, and I don't think there's anything wrong with that."

Kardashian and Odom openly admitted they wanted to conceive while still married and reportedly she has been telling friends she couldn't be happier. Odom, meanwhile, is also rumored to be thrilled and has vowed to remain sober.

No word on what any of this could mean for Kardashian and Harden's seemingly once budding relationship, although just this week an Australian model went public with claims she and the Houston Rockets All-Star guard have been intimate since he started openly dating the reality TV star.

RadarOnline reports "blonde Australian beauty" Rochelle Relf claims she and Harden hooked up after meeting at The Star Casino in Sydney sometime in June.

"Khloe was with James in Hawaii, then he flew to Australia and spent the night with me," the 23-year-old Australian told New Idea magazine. "He was charming and affectionate -- he asked me to visit him in America and told me that he was a single guy."

Relf added the two openly kissed and held hands after arriving at a local hotel and were so affectionate with one another that a security guard told them to stop touching, though Harden hardly listened.
