It was an unexpected moment when an estimated 20,000 basketball fans at the Staples Center in Los Angeles, California, booed sisters Khloe Kardashian and Kendall Jenner during the Game 3 between the Los Angeles Clippers and the Houston Rockets.

A Daily Mail source said most of the audience showed their disapproval when the camera focused on the two ladies.

The reaction from the crowd was so loud that the camera had to be panned away to the seats of Floyd Mayweather Jr. and Snoop Dogg, the site added.

Khloe and Kendall were reportedly embarassed and shocked with the crowd's hostility towards them.

InTouchWeekly recalled that Khloe used to be a welcomed personality during NBA games when she was still married to Lamar Odom. The celebrity could have expected a different greeting from basketball fans as she had been a regular in NBA games in the past years.

Despite the cold welcome of the Los Angeles crowd, the sisters still rose to the occasion with their individual fashion statements. Daily Mail said the supermodel wore knee-high gladiator boots with stiletto heels and tiny denim shorts which boasted her legs.

Kendall, who is also the new face of Calvin Klein, also wore a white crop top with a black jacket for cover. "She styled her hair in a high ponytail, allowing her chiselled features to shine, and carried a little black purse with furry green trim," added Daily Mail.

Khloe, on the other hand, was more covered compared to her sister as she wore a jacket over a sweater dress and had black knee-high heeled boots on.

On Bruce Jenner's transition

The two have been reportedly supportive of their patriach Bruce Jenner's transition into a woman. The former Olympian recently revealed that he identifies himself as a woman though the public was not shocked anymore since signs of his transition manifested early on even before his tell-all interview with ABC's Diane Sawyer.

Daily Mail noted that in the upcoming two-part "Keeping Up With The Kardashians: About Bruce" special, which will air on May 17 and 18, Bruce will reveal to his daughters Kendall and Kylie and his four stepchildren Khloe, Kim, Kourtney and Rob Kardashian his transgender identity.

A trailer of the TV series showed a teary-eyed Bruce who was seen opening up to Kylie and Kendall and even to Kourtney's longtime boyfriend Scott Disick.

"I don't like it when people say Bruce is going to be gone," Kendall said in the video.

The family seems to be in a tough time right now but they are certainly showing that they will always have Bruce's back even after his revelation.
