Khloe Kardashian is being "really sweet" to her estranged NBA husband Lamar Odom, according to HollywoodLife.com.

The irreconcilable differences Kardashian cited in formally filing for divorce from her husband of four years in December now seem like a distant memory, as some are even speculating the one-time celebrity couple may be planning to get back together.

Lamar leans on Bruce Jenner for support

"She's been checking up on him every day," a source told HollywoodLife, adding that the two now talk practically every day. "He wants to see her soon."

The 29-year-old Keeping Up With The Kardashians star recently purchased the home of Justin Bieber and has already begun installing a "subterranean basketball court."

The source later told HollywoodLife "her installing a basketball court really says something. He thinks he could get Khloe back."

Lamar Odom name used as code language for street drugs?

Now back in the states after a short run with a Spanish pro team that was ended by a back injury, the 34-year-old former NBA Sixth Man of the Year Award winner is also rumored to be receiving treatment and getting "healthy for the NBA."
