Lamar Odom resurfaces in L.A. amidst reports that his wife Khloe Kardashian does not aware of his whereabouts. Lamar reportedly went to a sushi restaurant called Octopus on Friday, September 6 for lunch. The eatery staff told TMZ that Lamar came with a male friend.

The athlete ordered miso soup and green tea, but he apparently had no appetite. The staff member said that Lamar barely touched the soup and only drank two cups of green tea. He kept chatting on his phone. A source told Us Weekly, "He didn't look very happy."

Another source, however, told E! News different account. The source said that Lamar was in his usual self. He was "smiling" and "very nice and polite." The source added that Lamar held a door open for a guest who was on the way out of Roosevelt Lofts, which is located next to Octopus.

A different source also said that Lamar "seemed upbeat" on Thursday night. "He was in a good mood and did not seem down at all. In fact, he even signed a fan's autograph. He was his normal self, nice and polite," the source explained.

Khloe and Lamar are said having marital problems because of Lamar's drug abuse and a recent report suggested that Khloe did not know her husband's whereabouts. "Khloe doesn't know where Lamar is. She's just exhausted. I don't think anyone knows where he is at this point," a source said on September 5. The source added, "She's not fazed by these reports. She doesn't believe it, she doesn't think he went to rehab. Khloe is so exhausted by everything. She doesn't know what's going on."
