Kendall Jenner recently stepped out with her brother-in-law Scott Disick to do a little shopping together, despite reports that speculated that they had a secret affair. The unlikely duo was spotted doing a little mid-day shopping at a local Barneys New York department store in Beverly Hills, Calif. on Monday.

And while there's a good chance that nothing ever went on between them, gossip blogs can't help but continue to stir the pot about their alleged "affair." Disick is in a long-term relationship with Jenner's sister, Kourtney Kardashian.

According to Hollywood Life on Tuesday, Jenner allegedly told Disick that they need to stop seeing each other because it was causing friction within the family.

A source told the site, "She actually told him to stop and said they had to end 'whatever this is. She begged him to go home to Kourtney and make things work, because she didn't know how they could carry on without destroying the family."

Back in February, Disick supposedly threated to expose all of Kendall and Kylie Jenner's secrets, which included a rumored pregnancy and drug abuse.

According to OK! Magazine's print edition (via Celebrity Dirty Laundry), Scott is allegedly fed up with the girls' antics and is seeking "revenge" after everything that he's supposedly endured with the Kardashian family.

A source told the magazine, "After eight years with the Kardashians, Scott Disick is ready to reveal their most scathing secrets. Scott wants revenge for all of the crap he has endured. He feels like he has been intentionally made to look like the 'bad guy' to boost ratings. Scott has told Kourtney that if she tries to take their kids and their money, he will let loose enough information humiliate her to take down her entire family."
