Awkward dinner date! Khloe Kardashian and Lamar Odom were decided to grab a late-night meal at an NYC restaurant on Monday, March 4 the same night Kim Kardashian's estranged husband Kris Humphries was dining there, a source tells Us Weekly.

According to the insider, Humphries was having dinner with a large group of friends at Catch in NYC's Meatpacking District when Khloe and Lamar arrived.

The couple of three years were initially unaware that Humphries was there, and were seated at the opposite end of the main dining room. However, the source tells Us that Khloe, 28, spotted Humphries when he stood up to greet a friend joining his group.

She "immediately looked down and used her cocktail menu to hide her face," the insider says.

Khloe and Lamar, 33, ate quickly and never engaged with their estranged brother-in-law before leaving the restaurant. The source tells Us that Humphries didn't seem bothered during his meal and was having a good time.

Kim, 32, filed for divorce from the 28-year-old NBA player in October 2011 after 72 days of marriage. Humphries countered with annulment based on fraud, and the two have been involved in a lengthy divorce trial since. On Feb. 15, however, a judge ruled that the former couples' trial will begin May 6.

Kim is currently expecting her first child with boyfriend Kanye West, and Khloe said her sister's divorce "needs to get over already."

"He's, in my opinion, delusional," Khloe said of Humphries on Watch What Happens Live on Jan. 31. "I don't know why he's asking for anything? He's fame-hungry, in my opinion. He wants money . . . I just think everything he's doing is so -- it's just gross to me."
