Kourtney Kardashian, who is rumored to be dating Justin Bieber, told her family to avoid taking the Canadian singer’s name on Christmas Day, Hollywood Life reported. Kardashian has reportedly been dating Bieber to annoy her former partner Scott Disick, with whom she has three children.

“Kourtney wanted to avoid having any outbursts or drama coming from Scott [Disick] on Christmas Day, so she asked everyone not to mention Justin Bieber’s name,” a source told Hollywood Life. “Basically his name was banned from the Kardashian household.”

Another source told the entertainment website that Disick has been trying to get in touch with Bieber over the 21-year-old’s alleged relationship with Kardashian. Bieber’s ex-girlfriend Selena Gomez had also confronted the "Sorry" singer over the matter and reportedly demanded answers from him over the dating rumors with Kardashian. Bieber reportedly began dating the 36-year-old Kardashian because he considered older women to be “dominant.”

Gomez, who thought Bieber’s relation with Kardashian as “incestuous,” cannot get over the fact that he was seeing Kardashian. “Selena can’t seem to get past the fact that Justin is dating Kourtney Kardashian. She talks about it all the time. At first she was shocked and didn’t believe it, but then she started to think about it and realized the writing was always on the wall. He’s always had a thing for older women,” a source reportedly said. “He even mentioned that he thought Kourtney was the best looking Kardashian. Selena just thought it was a schoolboy crush -- she never thought he’d act on it.”
