Khloe Kardashian Marriage Crisis: Lamar Odom Moves Back Into Marital Home -- Reconciliation In The Works?

Khloe Kardashian and Lamar Odom have taken a giant step toward an unlikely reconciliation after the reality star allowed her troubled husband to move back -- for now -- into the couple's multi-million dollar mansion, RadarOnline.com has exclusively learned.

Odom, 33, was spotted late on Monday afternoon driving into the gated community where he and Khloe, 29, live. A source close to the couple confirmed to RadarOnline.com that he was still at the Tarzana, Calif., home as of Tuesday afternoon.

The apparent reunion followed Odom's ultimatum to his wife of four years, as we first reported.

"Let me move back into the house or I am going to file for divorce," the ex-Los Angeles Clipper star told Khloe, according to a source.

In the wake of two women coming forward to sensationally claim that he had bedded them, the two-time NBA championship star had moved into a hotel while Kardashian lived at the marital home.

She had been "refusing to let Lamar even set foot in the house right now," the source said. But Odom had grown "tired of living in hotels" and threatened to "file for divorce because he is tired of the situation."

Tellingly, Kardashian was also spotted on Tuesday wearing her wedding ring, just four days after taking it off.

Odom returned home after a failed intervention by teammates from the Los Angeles Clippers, his former team the Los Angeles Lakers and agent Jeff Schwartz on Monday afternoon at a Los Angeles hotel, who all encouraged him to seek treatment for an addiction to OxyContin.

The dramatic talks  lasted three hours during which Odom appeared to be under the influence of a substance, a source inside the room said.

"There was a bit of time it appeared that Lamar was going to admit publicly his addiction and go to rehab, again," the source told RadarOnline.com. "But then, he abruptly bolted from the hotel and left the premises."
