Kourtney Kardashian Awkwardly Addresses Those Justin Bieber Hookup Rumors

The reality star also revealed what she knows about Kendall Jenner and Harry Styles' maybe-fling.

Unexpected celebrity hookups are as old as time itself, but one that’s really boggled our minds recently is Kourtney Kardashian’s rumored fling with Justin Bieber.

The 36-year-old reality star and 21-year-old singer first sparked rumors after hanging out in October, just months after her split from Scott Disick. They've been spotted out together sporadically since then, leaving everyone to wonder: Are they or aren’t they?

Never one to shy away from asking the tough questions, Ellen DeGeneres attempted to solve the mystery when Kourtney visited her show, for an episode airing Monday afternoon. Asked if Justin ever helps out babysitting her three kids, Kourtney immediately broke out into a huge grin and started blushing.

“We’re friends. Yes,” she told Ellen, to which the host replied, "You're smiling as if maybe it's beyond friends.”

“I've been smiling this whole time since I've been sitting here," Kourt retorted, before reaching for a glass of water. Hmm… looks like someone may need to work on her poker face.

Elsewhere in their conversation, Kourtney was similarly tight-lipped about her little sister Kendall Jenner’s rumored romance with Harry Styles. When asked if #Hendall is really happening, Kourtney admitted the One Direction singer is “good-looking,” but insisted she doesn’t know more beyond that.

“You know more than I do,” she told Ellen. “I’m telling you.”

Kourtney may be right about that — Harry and Kendall were spotted together in St. Barts in December, aboard the same private yacht that Ellen and her wife, Portia de Rossi, were also seen on. Watch out, Ellen... we might need to put you in the hot seat next.
