Kris Jenner Helps Rob Promotes His Sock Line

Kris Jenner is swooping in to help Rob Kardashian make a quick buck off the holiday shopping season, plugging her son's sock line after he filed docs to have his child support payments to Blac Chyna lessened.

Kris and Rob unleashed a social media ad blitz Thursday, promoting a line of Christmas-themed socks that were just released by Arthur George, the clothing company Kris just bought a stake in.

Kris and Rob teaming up to sell socks comes days after Rob went to court seeking to get a reduction in child support payments to Chyna ... he said he was basically broke after previously agreeing to pay Chyna $20,000 a month to support 2-year-old Dream. We guess business is about to get better now, so child support can stay!
