Kim Kardashian's estranged husband ignored her brother-in-law at a New York restaurant.

The reality TV star's soon to be ex-husband Kris Humphries - who is trying to prove she only married him to boost her ratings - came face to face with her sister Khloe's husband Lamar Odom at trendy eatery Catch on Monday night (04.03.13) but they did not acknowledge one another.

A source told gossip website Kris, 28, who plays basketball for the Brooklyn Nets and Lamar, 33, who plays for the Los Angeles Clippers ''sat at completely separate tables and didn't utter a single word to each other''.

The insider revealed that both NBA stars finished their meals and left around the same time ''without incident.''

Lamar took Kris under his wing during the run up to his wedding to Kim, who is now pregnant with her first child with her boyfriend Kanye West, and even gave him advice about how to handle to spotlight.

Kris was recently said to be willing to risk his career over his divorce battle.

The sports star is keen to have their 72-day marriage annulled on the grounds of fraud and their split has been dragging on since October 2011 because Kim wants a divorce.

His team is on track to score a place in the 2013 Playoffs, which run from April 20th to June 20th, and he is allegedly willing to miss the games in order to face her in court on May 6th.
