Kim Kardashian Skips Sister-In-Law Kaela Humphries Runway Debut In Richie Rich Show

Kim Kardashian has been a great older sister, sitting front row for Kendall and Kylie Jenner who both made their runway debuts walking in the Abbey Dawn and Sherri Hill fashion shows. It seems that sisterly love may not extend to Kim's new sister-in-law Kaela Humphries.

Kim's husband Kris Humphries and his father were the only family members who made it to Kaela's own runway debut in the Richie Rich show, reports Page Six.

Kris attended both Kendall and Kylie's walking debuts during New York Fashion Week, and was spotted on his cellphone, presumably trying to reach Kim, who was also supposed to sit front row.

Page Six reports that Kim was supposed to bring her sisters to the show, leaving three seats empty.

Kourtney Kardashian had a valid excuse for missing the event: she was taking her 21-month-old son Mason to the doctor, after he fell and hurt his nose. No word however on what caused Kim to miss the show.

Kim and her sisters were supposed to come and sit front-row [at Richie Rich]” said a spy, “but there were three empty seats.” They added that they saw the NBA star on his cellphone, presumably to reach Kim. “He’s always there to support her family,” said the spy, “and she wasn’t there for his.” Kourtney had to tend to son Mason, who fell and needed medical attention. But the Richie Rich show had more surprises when fellow model Coco, aka Ice-T’s wife, had a wardrobe malfunction on the catwalk, baring one of her ample assets while she was being carried by two hulking studs in tight underwear.
