Kim Kardashian and Kanye West attended a funeral for their 17-month-old nephew, Avery, who died in his sleep a week ago. The powerhouse couple sported all black for the family affair which was held in Los Angeles.

During the outing, Kim wore an ankle-length black dress, a fur overcoat and black sunglasses. Her long black hair was straightened loose down her back. Kanye, meanwhile, sported an all-black suit and large amber shades for the funeral.

Avery is the son of Kanye's cousin Ricky Anderson, who is currently works with the "Famous" hitmaker at his label, G.O.O.D. Music, in Los Angeles. His son passed away after showing no previous signs of illness.

Rumor has it, Kim's "pulling the plug" on her marriage to Kanye. The "breaking point" was reportedly last Sunday's "Keeping Up with the Kardashians," which focused on the 36-year-old socialite's Paris robbery last October.

A so-called family source told InTouch, "He'd told Kim her experience was personal and warned her, 'Do not exploit this for ratings.' But she did anyway. She went directly against his wishes and exposed every detail on camera. They had a huge fight, and he stormed out."

"Kim is seeking divorce," continued the source, "Kim didn't want to file while Kanye was having serious mental health problems, because that obviously would have been very tough for him to deal with. [Now] Kim knows the time is finally right for her to leave Kanye. She's been talking to her lawyer, and divorce papers have been drawn up."
