Awkward alert!

Newly engaged New Jersey Nets forward Kris Humphries encountered Kim Kardashian's one-time love Reggie Bush on Tuesday night at Skybar's Champagne & Caviar party in West Hollywood — and the mood was icier than ever.

Bush, 26, was the first to arrive at 11:45 with a couple of friends (including The Hills' Frankie Delgado). The low-key NFL player kept his hood up as he sat back and sipped on his drink while texting on his BlackBerry.

"He was pretty quiet and tame and kept to himself," an eyewitness tells Us Weekly. "He mostly spoke to the promoters that he is already acquainted with."

When Humphries, 26, arrived 15 minutes later, he was escorted to the same area where Bush had been seated earlier.

"Kris was pretty much standing in front of Reggie's table, yet they never came into contact or ever spoke," the eyewitness notes. "Once Kris got there Reggie didn't move from his table at all. He was on his phone the entire time until he left."

Bush — who dated Kardashian, 30, on-and-off for three years until March 2010 — was the first to leave at 1:05; Humphries and his friend followed suit at 1:30.
