Sources reveal exclusively to Life & Style magazine that the KUWTK star is in a love triangle with ex Scott Disick and the "What Do You Mean" singer, who is 15 years her junior.
"At first, everyone just assumed it was Scott's since he's been trying to make things work, but then out of the blue, she jets off to spend time with Justin," the insider says. "Her close friends and even her sisters aren't sure anymore."
Since their breakup one year ago, Scott has stopped drinking and using drugs, according to another source, but seeing the mother-of-three with the much-younger singer has not been easy for him.
"It's heartbreaking for him to see Kourtney with Justin," explains the source, adding that the 33-year-old desperately hopes he's the father of her baby.
"A paternity test is the only answer at this point, but it's the last thing in the world she wants to do," the source continues. "This whole thing has her stressed out like you wouldn't believe!"[lifeandstylemag]
