Kourtney Kardashian can't hide huge smile when Ellen DeGeneres brings up Justin Bieber

Kourtney Kardashian will appear on Monday’s Ellen DeGeneres Show, where the daytime talk show host pressed her about her rumored relationship with Justin Bieber.

After she called her ex, Scott Disick “family,” Kardashian also talked about her rumored fling with the “Sorry” singer.

When DeGeneres brought up Bieber, Kardashian broke out in a huge smile. “We're friends," she said, but DeGeneres prodded a little more, asking “Why are you smiling that way? You're smiling as if that maybe it's beyond friends.”

The mom of three replied, "I've been smiling this whole time since I've been sitting here."
